+
+=head1 DESCRIPTION
+
+Several OpenSSL structures can have application-specific data attached to them,
+known as "exdata."
+The specific structures are:
+
+ SSL
+ SSL_CTX
+ SSL_SESSION
+ X509
+ X509_STORE
+ X509_STORE_CTX
+ DH
+ DSA
+ ECDH
+ ECDSA
+ RSA
+ ENGINE
+ UI
+ BIO
+
+Each is identified by an B<CRYPTO_EX_INDEX_xxx> define in the B<crypto.h>
+header file. In addition, B<CRYPTO_EX_INDEX_APP> is reserved for
+applications to use this facility for their own structures.
+
+The API described here is used by OpenSSL to manipulate exdata for specific
+structures. Since the application data can be anything at all it is passed
+and retrieved as a B<void *> type.
+
+Exdata types are identified by an B<index>, an integer guaranteed to be
+unique within structures for the lifetime of the program. Applications
+using exdata typically call B<CRYPTO_get_ex_new_index> at startup, and
+store the result in a global variable, or write a wrapper function to
+provide lazy evaluation. The B<class_index> should be one of the
+B<CRYPTO_EX_INDEX_xxx> values. The B<argl> and B<argp> parameters are saved
+to be passed to the callbacks but are otherwise not used. In order to
+transparently manipulate exdata, three callbacks must be provided. The
+semantics of those callbacks are described below.
+
+When copying or releasing objects with exdata, the callback functions
+are called in increasing order of their B<index> value.
+
+If a dynamic library can be unloaded, it should call CRYPTO_free_ex_index()
+when this is done.
+This will replace the callbacks with no-ops
+so that applications don't crash. Any existing exdata will be leaked.
+
+To set or get the exdata on an object, the appropriate type-specific
+routine must be used. This is because the containing structure is opaque
+and the B<CRYPTO_EX_DATA> field is not accessible. In both API's, the
+B<idx> parameter should be an already-created index value.
+
+When setting exdata, the pointer specified with a particular index is saved,
+and returned on a subsequent "get" call. If the application is going to
+release the data, it must make sure to set a B<NULL> value at the index,
+to avoid likely double-free crash.
+
+The function B<CRYPTO_free_ex_data> is used to free all exdata attached
+to a structure. The appropriate type-specific routine must be used.
+The B<class_index> identifies the structure type, the B<obj> is
+be the pointer to the actual structure, and B<r> is a pointer to the
+structure's exdata field.
+
+=head2 Callback Functions
+
+This section describes how the callback functions are used. Applications
+that are defining their own exdata using B<CYPRTO_EX_INDEX_APP> must
+call them as described here.
+
+When a structure is initially allocated (such as RSA_new()) then the
+new_func() is called for every defined index. There is no requirement
+that the entire parent, or containing, structure has been set up.
+The new_func() is typically used only to allocate memory to store the
+exdata, and perhaps an "initialized" flag within that memory.
+The exdata value should be set by calling CRYPTO_set_ex_data().
+
+When a structure is free'd (such as SSL_CTX_free()) then the
+free_func() is called for every defined index. Again, the state of the
+parent structure is not guaranteed. The free_func() may be called with a
+NULL pointer.
+
+Both new_func() and free_func() take the same parameters.
+The B<parent> is the pointer to the structure that contains the exdata.
+The B<ptr> is the current exdata item; for new_func() this will typically
+be NULL. The B<r> parameter is a pointer to the exdata field of the object.
+The B<idx> is the index and is the value returned when the callbacks were
+initially registered via CRYPTO_get_ex_new_index() and can be used if
+the same callback handles different types of exdata.
+
+dup_func() is called when a structure is being copied. This is only done
+for B<SSL> and B<SSL_SESSION> objects. The B<to> and B<from> parameters
+are pointers to the destination and source B<CRYPTO_EX_DATA> structures,
+respectively. The B<srcp> parameter is a pointer to the source exdata.
+When the dup_func() returns, the value in B<srcp> is copied to the
+destination ex_data. If the pointer contained in B<srcp> is not modified,
+then both B<to> and B<from> will point to the same data. The B<idx>,
+B<argl> and B<argp> parameters are as described for the other two callbacks.
+
+=head1 RETURN VALUES
+
+CRYPTO_get_ex_new_index() returns a new index or -1 on failure; the
+value B<0> is reserved for the legacy "app_data" API's.
+
+CRYPTO_free_ex_index() and
+CRYPTO_set_ex_data() return 1 on success or 0 on failure.
+
+CRYPTO_get_ex_data() returns the application data or NULL on failure;
+note that NULL may be a valid value.
+
+dup_func() should return 0 for failure and 1 for success.

-Several OpenSSL structures can have application specific data attached to them.
-These functions are used internally by OpenSSL to manipulate application
-specific data attached to a specific structure.
-
-These functions should only be used by applications to manipulate
-B<CRYPTO_EX_DATA> structures passed to the new_func(), free_func() and
-dup_func() callbacks: as passed to RSA_get_ex_new_index() for example.
-
-CRYPTO_set_ex_data() is used to set application specific data, the data is
-supplied in the B<arg> parameter and its precise meaning is up to the
-application.
-
-CRYPTO_get_ex_data() is used to retrieve application specific data. The data
-is returned to the application, this will be the same value as supplied to
-a previous CRYPTO_set_ex_data() call.
-
-=head1 RETURN VALUES
-
-CRYPTO_set_ex_data() returns 1 on success or 0 on failure.
-
-CRYPTO_get_ex_data() returns the application data or 0 on failure. 0 may also
-be valid application data but currently it can only fail if given an invalid B<idx>
-parameter.
-
-On failure an error code can be obtained from L<ERR_get_error(3)>.

-
-=head1 DESCRIPTION
-
-Several OpenSSL structures can have application specific data attached to them.
-This has several potential uses, it can be used to cache data associated with
-a structure (for example the hash of some part of the structure) or some
-additional data (for example a handle to the data in an external library).
-
-Since the application data can be anything at all it is passed and retrieved
-as a B<void *> type.
-
-The RSA_get_ex_new_index() function is initially called to "register" some
-new application specific data. It takes three optional function pointers which
-are called when the parent structure (in this case an RSA structure) is
-initially created, when it is copied and when it is freed up. If any or all of
-these function pointer arguments are not used they should be set to NULL. The
-precise manner in which these function pointers are called is described in more
-detail below. RSA_get_ex_new_index() also takes additional long and pointer
-parameters which will be passed to the supplied functions but which otherwise
-have no special meaning. It returns an B<index> which should be stored
-(typically in a static variable) and passed used in the B<idx> parameter in
-the remaining functions. Each successful call to RSA_get_ex_new_index()
-will return an index greater than any previously returned, this is important
-because the optional functions are called in order of increasing index value.
-
-RSA_set_ex_data() is used to set application specific data, the data is
-supplied in the B<arg> parameter and its precise meaning is up to the
-application.
-
-RSA_get_ex_data() is used to retrieve application specific data. The data
-is returned to the application, this will be the same value as supplied to
-a previous RSA_set_ex_data() call.
-
-new_func() is called when a structure is initially allocated (for example
-with RSA_new(). The parent structure members will not have any meaningful
-values at this point. This function will typically be used to allocate any
-application specific structure.
-
-free_func() is called when a structure is being freed up. The dynamic parent
-structure members should not be accessed because they will be freed up when
-this function is called.
-
-new_func() and free_func() take the same parameters. B<parent> is a
-pointer to the parent RSA structure. B<ptr> is a the application specific data
-(this wont be of much use in new_func(). B<ad> is a pointer to the
-B<CRYPTO_EX_DATA> structure from the parent RSA structure: the functions
-CRYPTO_get_ex_data() and CRYPTO_set_ex_data() can be called to manipulate
-it. The B<idx> parameter is the index: this will be the same value returned by
-RSA_get_ex_new_index() when the functions were initially registered. Finally
-the B<argl> and B<argp> parameters are the values originally passed to the same
-corresponding parameters when RSA_get_ex_new_index() was called.
-
-dup_func() is called when a structure is being copied. Pointers to the
-destination and source B<CRYPTO_EX_DATA> structures are passed in the B<to> and
-B<from> parameters respectively. The B<from_d> parameter is passed a pointer to
-the source application data when the function is called, when the function returns
-the value is copied to the destination: the application can thus modify the data
-pointed to by B<from_d> and have different values in the source and destination.
-The B<idx>, B<argl> and B<argp> parameters are the same as those in new_func()
-and free_func().
-
-=head1 RETURN VALUES
-
-RSA_get_ex_new_index() returns a new index or -1 on failure (note 0 is a valid
-index value).
-
-RSA_set_ex_data() returns 1 on success or 0 on failure.
-
-RSA_get_ex_data() returns the application data or 0 on failure. 0 may also
-be valid application data but currently it can only fail if given an invalid B<idx>
-parameter.
-
-new_func() and dup_func() should return 0 for failure and 1 for success.
-
-On failure an error code can be obtained from L<ERR_get_error(3)>.
-
-=head1 BUGS
-
-dup_func() is currently never called.
-
-The return value of new_func() is ignored.
-
-The new_func() function isn't very useful because no meaningful values are
-present in the parent RSA structure when it is called.

-SSL_get_ex_data_X509_STORE_CTX_idx - get ex_data index to access SSL structure
-from X509_STORE_CTX
-
-=head1 SYNOPSIS
-
- #include <openssl/ssl.h>
-
- int SSL_get_ex_data_X509_STORE_CTX_idx(void);
-
-=head1 DESCRIPTION
-
-SSL_get_ex_data_X509_STORE_CTX_idx() returns the index number under which
-the pointer to the SSL object is stored into the X509_STORE_CTX object.
-
-=head1 NOTES
-
-Whenever a X509_STORE_CTX object is created for the verification of the
-peers certificate during a handshake, a pointer to the SSL object is
-stored into the X509_STORE_CTX object to identify the connection affected.
-To retrieve this pointer the X509_STORE_CTX_get_ex_data() function can
-be used with the correct index. This index is globally the same for all
-X509_STORE_CTX objects and can be retrieved using
-SSL_get_ex_data_X509_STORE_CTX_idx(). The index value is set when
-SSL_get_ex_data_X509_STORE_CTX_idx() is first called either by the application
-program directly or indirectly during other SSL setup functions or during
-the handshake.
-
-The value depends on other index values defined for X509_STORE_CTX objects
-before the SSL index is created.
-
-=head1 RETURN VALUES
-

-=item E<gt>=0
-
-The index value to access the pointer.

-
-=head1 EXAMPLES
-
-The index returned from SSL_get_ex_data_X509_STORE_CTX_idx() allows to
-access the SSL object for the connection to be accessed during the
-verify_callback() when checking the peers certificate. Please check
-the example in L<SSL_CTX_set_verify(3)>,
