SYNOPSIS
#include

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.
