CRYPTO_GET_MEM_FUNCTIONS(3)                 DragonFly Library Functions Manual

NAME

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

SYNOPSIS

#include <openssl/crypto.h> void CRYPTO_get_mem_functions(void *(**m)(size_t), void *(**r)(void *, size_t), void (**f)(void *)); int CRYPTO_set_mem_functions(void *(*m)(size_t), void *(*r)(void *, size_t), void (*f)(void *)); 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_get_mem_functions() assigns pointers to the C library functions malloc(3), realloc(3), and free(3) to those of its arguments that are not NULL. 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.
