NAME¶

OPENSSL_malloc, OPENSSL_realloc, OPENSSL_free, OPENSSL_strdup, CRYPTO_malloc, CRYPTO_realloc, CRYPTO_free, CRYPTO_strdup — legacy OpenSSL memory allocation wrappers

SYNOPSIS¶

#include <openssl/crypto.h>

void *
OPENSSL_malloc(size_t num);

void *
OPENSSL_realloc(void *addr, size_t num);

void
OPENSSL_free(void *addr);

char *
OPENSSL_strdup(const char *str);

void *
CRYPTO_malloc(size_t num, const char *file, int line);

void *
CRYPTO_realloc(void *p, size_t num, const char *file, int line);

void
CRYPTO_free(void *str, const char *, int);

char *
CRYPTO_strdup(const char *p, const char *file, int line);

DESCRIPTION¶

Do not use any of the interfaces documented here in new code. They are provided purely for compatibility with legacy application code.

All 8 of these functions are wrappers around the corresponding standard malloc(3), realloc(3), free(3), and strdup(3) functions.

The four OPENSSL_*() functions are implemented as macros.

RETURN VALUES¶

These functions return the same type and value as the corresponding standard functions.

SEE ALSO¶

crypto(3)

HISTORY¶

CRYPTO_malloc(), CRYPTO_realloc(), and CRYPTO_free() first appeared in SSLeay 0.6.4 and have been available since OpenBSD 2.4.

OPENSSL_malloc(), OPENSSL_realloc(), 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.

CAVEATS¶

If interoperability with other implementations is required, memory returned by the library as bare pointers must be freed with OPENSSL_free().
