-
- #include <openssl/buffer.h>
-
- BUF_MEM *BUF_MEM_new(void);
-
- void	BUF_MEM_free(BUF_MEM *a);
-
- int	BUF_MEM_grow(BUF_MEM *str, int len);
-
- char *BUF_strdup(const char *str);
-
- char *BUF_strndup(const char *str, size_t siz);
-
- void *BUF_memdup(const void *data, size_t siz);
-
- size_t BUF_strlcpy(char *dst, const char *src, size_t size);
-
- size_t BUF_strlcat(char *dst, const char *src, size_t size);
-
- size_t BUF_strnlen(const char *str, size_t maxlen);

-=head1 DESCRIPTION
-
-The buffer library handles simple character arrays. Buffers are used for
-various purposes in the library, most notably memory BIOs.
-
-BUF_MEM_new() allocates a new buffer of zero size.
-
-BUF_MEM_free() frees up an already existing buffer. The data is zeroed
-before freeing up in case the buffer contains sensitive data.
-
-BUF_MEM_grow() changes the size of an already existing buffer to
-B<len>. Any data already in the buffer is preserved if it increases in
-size.
-
-BUF_strdup(), BUF_strndup(), BUF_memdup(), BUF_strlcpy(),
-BUF_strlcat() and BUF_strnlen are equivalents of the standard C
-library functions. The dup() functions use OPENSSL_malloc() underneath
-and so should be used in preference to the standard library for memory
-leak checking or replacing the malloc() function.
-
-Memory allocated from these functions should be freed up using the
-OPENSSL_free() function.
-
-BUF_strndup makes the explicit guarantee that it will never read past
-the first B<siz> bytes of B<str>.
-
-=head1 RETURN VALUES
-
-BUF_MEM_new() returns the buffer or NULL on error.
-
-BUF_MEM_free() has no return value.
-
-BUF_MEM_grow() returns zero on error or the new size (i.e. B<len>).
-

-
-L<bio(3)|bio(3)>
-
-=head1 HISTORY
-
-BUF_MEM_new(), BUF_MEM_free() and BUF_MEM_grow() are available in all
-versions of SSLeay and OpenSSL. BUF_strdup() was added in SSLeay 0.8.
