Do not use any of the interfaces documented here in new code. They
are provided purely for compatibility with legacy application code.
These functions are wrappers around the corresponding standard
malloc(3),
free(3),
and
strdup(3)
functions.
The
OPENSSL_*
()
functions are implemented as macros.
These functions return the same type and value as the
corresponding standard functions.
CRYPTO_malloc
() and
CRYPTO_free
() first appeared in SSLeay 0.6.4 and
have been available since OpenBSD 2.4.
OPENSSL_malloc
() and
OPENSSL_free
() first appeared in OpenSSL 0.9.6 and
have been available since OpenBSD 2.9.
CRYPTO_strdup
() and
OPENSSL_strdup
() first appeared in OpenSSL 0.9.8j
and have been available since OpenBSD 4.5.
If interoperability with other implementations is required, memory
returned by the library as bare pointers must be freed with
OPENSSL_free
().
