gnutls_global_set_mem_functions - API function

#include <gnutls/compat.h>

void gnutls_global_set_mem_functions(gnutls_alloc_function alloc_func, gnutls_alloc_function secure_alloc_func, gnutls_is_secure_function is_secure_func, gnutls_realloc_function realloc_func, gnutls_free_function free_func);

it's the default memory allocation function. Like malloc().
This is the memory allocation function that will be used for sensitive data.
a function that returns 0 if the memory given is not secure. May be NULL.
A realloc function
The function that frees allocated data. Must accept a NULL pointer.

since 3.3.0 it is no longer possible to replace the internally used memory allocation functions

This is the function where you set the memory allocation functions gnutls is going to use. By default the libc's allocation functions (malloc(), free()), are used by gnutls, to allocate both sensitive and not sensitive data. This function is provided to set the memory allocation functions to something other than the defaults

This function must be called before gnutls_global_init() is called. This function is not thread safe.
