CRYPTO_SET_MEM_FUNCTIONS(3)

NAME
CRYPTO_set_mem_functions, CRYPTO_mem_ctrl, CRYPTO_mem_leaks, CRYPTO_mem_leaks_fp, CRYPTO_mem_leaks_cb - legacy OpenSSL memory allocation control

SYNOPSIS
libcrypto
#include <openssl/crypto.h>
int
CRYPTO_set_mem_functions(void *(*m)(size_t, const char *, int), void *(*r)(void *, size_t, const char *, int), void (*f)(void *, const char *, int));
int
CRYPTO_mem_ctrl(int mode);
int
CRYPTO_mem_leaks(BIO *b);
int
CRYPTO_mem_leaks_fp(FILE *fp);
typedef int *
CRYPTO_MEM_LEAK_CB(unsigned long, const char *, int, int, void *);
int
CRYPTO_mem_leaks_cb(CRYPTO_MEM_LEAK_CB *cb);

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

CRYPTO_set_mem_functions(), CRYPTO_mem_ctrl(), CRYPTO_mem_leaks(), CRYPTO_mem_leaks_fp(), and CRYPTO_mem_leaks_cb() have no effect.

RETURN VALUES
CRYPTO_set_mem_functions() always returns 0.

CRYPTO_mem_ctrl() always returns CRYPTO_MEM_CHECK_OFF.

CRYPTO_mem_leaks(), CRYPTO_mem_leaks_fp(), and CRYPTO_mem_leaks_cb() always return -1.
