BUF_MEM_new, BUF_MEM_new_ex, BUF_MEM_free, BUF_MEM_grow - simple
character array structure
-BUF_strdup, BUF_strndup, BUF_memdup, BUF_strlcpy, BUF_strlcat -
standard C library equivalents
=head1 SYNOPSIS
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
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.
=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.
-
-BUF_MEM_new_ex() was contributed to OpenSSL by Akamai Technologies
-in May, 2014.
+BUF_MEM_new_ex() was added in OpenSSL 1.1.0.
