These functions allow an B<ASN1_STRING> structure to be manipulated.
-ASN1_STRING_length() returns the length of the content of B<x>.
+ASN1_STRING_length() returns the length of the content of I<x>.
-ASN1_STRING_get0_data() returns an internal pointer to the data of B<x>.
+ASN1_STRING_get0_data() returns an internal pointer to the data of I<x>.
Since this is an internal pointer it should B<not> be freed or
modified in any way.
returned value is not constant. This function is deprecated:
applications should use ASN1_STRING_get0_data() instead.
-ASN1_STRING_dup() returns a copy of the structure B<a>.
+ASN1_STRING_dup() returns a copy of the structure I<a>.
-ASN1_STRING_cmp() compares B<a> and B<b> returning 0 if the two
+ASN1_STRING_cmp() compares I<a> and I<b> returning 0 if the two
are identical. The string types and content are compared.
-ASN1_STRING_set() sets the data of string B<str> to the buffer
-B<data> or length B<len>. The supplied data is copied. If B<len>
+ASN1_STRING_set() sets the data of string I<str> to the buffer
+I<data> or length I<len>. The supplied data is copied. If I<len>
is -1 then the length is determined by strlen(data).
-ASN1_STRING_type() returns the type of B<x>, using standard constants
+ASN1_STRING_type() returns the type of I<x>, using standard constants
such as B<V_ASN1_OCTET_STRING>.
-ASN1_STRING_to_UTF8() converts the string B<in> to UTF8 format, the
-converted data is allocated in a buffer in B<*out>. The length of
-B<out> is returned or a negative error code. The buffer B<*out>

should be freed using OPENSSL_free().

is null terminated or does not contain embedded nulls. The actual format
of the data will depend on the actual string type itself: for example

Similar care should be take to ensure the data is in the correct format
when calling ASN1_STRING_set().

-ASN1_STRING_dup() returns a valid B<ASN1_STRING> structure or B<NULL> if an
+ASN1_STRING_dup() returns a valid B<ASN1_STRING> structure or NULL if an
error occurred.
ASN1_STRING_cmp() returns an integer greater than, equal to, or less than 0,

ASN1_STRING_set() returns 1 on success or 0 on error.
-ASN1_STRING_type() returns the type of B<x>.

negative value if an error occurred.
