 This is some preliminary documentation for OpenSSL.
 
-==============================================================================
-                            BUFFER Library
-==============================================================================
-
-The buffer library handles simple character arrays. Buffers are used for
-various purposes in the library, most notably memory BIOs.
-
-The library uses the BUF_MEM structure defined in buffer.h:
-
-typedef struct buf_mem_st
-{
-        int length;     /* current number of bytes */
-        char *data;
-        int max;        /* size of buffer */
-} BUF_MEM;
-
-'length' is the current size of the buffer in bytes, 'max' is the amount of
-memory allocated to the buffer. There are three functions which handle these
-and one "miscellaneous" function.
-
-BUF_MEM *BUF_MEM_new()
-
-This allocates a new buffer of zero size. Returns the buffer or NULL on error.
-
-void BUF_MEM_free(BUF_MEM *a)
-
-This frees up an already existing buffer. The data is zeroed before freeing
-up in case the buffer contains sensitive data.
-
-int BUF_MEM_grow(BUF_MEM *str, int len)
-
-This changes the size of an already existing buffer. It returns zero on error
-or the new size (i.e. 'len'). Any data already in the buffer is preserved if
-it increases in size.
-
-char * BUF_strdup(char *str)
-
-This is the previously mentioned strdup function: like the standard library
-strdup() it copies a null terminated string into a block of allocated memory
-and returns a pointer to the allocated block.
-
-Unlike the standard C library strdup() this function uses Malloc() and so
-should be used in preference to the standard library strdup() because it can
-be used for memory leak checking or replacing the malloc() function.
-
-The memory allocated from BUF_strdup() should be freed up using the Free()
-function.
