NAME
       libkeccak_hmac_create - Allocate and initialise HMAC-hashing state

SYNOPSIS
       #include <libkeccak.h>

       struct libkeccak_hmac_state *libkeccak_hmac_create(const struct libkeccak_spec *spec, const void *key, size_t key_length);

       Link with -lkeccak.

DESCRIPTION
       The libkeccak_hmac_create() function allocates a new struct
       libkeccak_hmac_state * with one initialised element, and sets the
       algorithm tuning parameters to those specified by *spec, and the key to
       key of length key_length.

RETURN VALUES
       The libkeccak_hmac_create() function returns a newly allocated struct
       libkeccak_hmac_state * (of one initialised element) upon successful
       completion.  On error, NULL is returned and errno is set to describe
       the error.
