void * gcry_malloc (size_t n) ¶This function tries to allocate n bytes of memory. On success
it returns a pointer to the memory area, in an out-of-core condition,
it returns NULL.
void * gcry_malloc_secure (size_t n) ¶Like gcry_malloc, but uses secure memory.
void * gcry_calloc (size_t n, size_t m) ¶This function allocates a cleared block of memory (i.e., initialized with
zero bytes) long enough to contain a vector of n elements, each of
size m bytes. On success it returns a pointer to the memory
block; in an out-of-core condition, it returns NULL.
void * gcry_calloc_secure (size_t n, size_t m) ¶Like gcry_calloc, but uses secure memory.
void * gcry_realloc (void *p, size_t n) ¶This function tries to resize the memory area pointed to by p to
n bytes. On success it returns a pointer to the new memory
area, in an out-of-core condition, it returns NULL. Depending on
whether the memory pointed to by p is secure memory or not,
gcry_realloc tries to use secure memory as well.
void gcry_free (void *p) ¶Release the memory area pointed to by p.
