NAME         top

       gnutls_hash_squeeze - API function

SYNOPSIS         top

       #include <gnutls/crypto.h>

       int gnutls_hash_squeeze(gnutls_hash_hd_t handle, void * output,
       size_t length);

ARGUMENTS         top

       gnutls_hash_hd_t handle
                   a gnutls_hash_hd_t

       void * output
                   destination to store the output; must be equal to or
                   larger than  length

       size_t length
                   length of  output

DESCRIPTION         top

       This function will extract digest output of  length bytes. The
       handle must be initialized with gnutls_hash_init() as an extended
       output function (XOF), such as GNUTLS_DIG_SHAKE_128 or
       GNUTLS_DIG_SHAKE_256.

       This function can be called multiple times. To reset the state of
       handle , call gnutls_hash_deinit() with NULL as the digest
       argument.

RETURNS         top

       GNUTLS_E_SUCCESS (0) on success; negative error code otherwise.

SINCE         top
