NAME
       crypto_shash_export - extract operational state for message digest

SYNOPSIS
       int crypto_shash_export(struct shash_desc * desc, void * out);

ARGUMENTS
       desc
           reference to the operational state handle whose state is exported

       out
           output buffer of sufficient size that can hold the hash state

DESCRIPTION
       This function exports the hash state of the operational state handle into the
       caller-allocated output buffer out which must have sufficient size (e.g. by calling
       crypto_shash_descsize).

RETURN
       0 if the export creation was successful; < 0 if an error occurred
