OPENSSL_MALLOC(3) Library Functions Manual OPENSSL_MALLOC(3)
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.
RETURN VALUES
These functions return the same type and value as the corresponding standard functions.

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(). GNU November 6, 2022 OPENSSL_MALLOC(3)
