NAME
       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
SYNOPSIS
        #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);
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 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 siz bytes of str.
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. len).

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.
