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
.
Like gcry_malloc
, but uses secure memory.
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
.
Like gcry_calloc
, but uses secure memory.
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.
Release the memory area pointed to by p.
