AHASH_REQUEST_SET_CR(9)               Programming Interface               AHASH_REQUEST_SET_CR(9)



NAME
       ahash_request_set_crypt - set data buffers

SYNOPSIS
       void ahash_request_set_crypt(struct ahash_request * req, struct scatterlist * src,
                                    u8 * result, unsigned int nbytes);

ARGUMENTS
       req
           ahash_request handle to be updated

       src
           source scatter/gather list

       result
           buffer that is filled with the message digest -- the caller must ensure that the
           buffer has sufficient space by, for example, calling crypto_ahash_digestsize

       nbytes
           number of bytes to process from the source scatter/gather list

DESCRIPTION
       By using this call, the caller references the source scatter/gather list. The source
       scatter/gather list points to the data the message digest is to be calculated for.
