The message specified by the -.I msg -parameter with the byte-size specified by the -.I msglen -parameter, will be hashed. -.PP -The -.BR libkeccak_fast_update () -function may reallocate the state's message chunk buffer. -When doing so, it attempts to do so as quickly as possible, -rather than ensuring that the information in the old -allocation is securely removed if a new allocation is required. -.SH RETURN VALUES -The -.BR libkeccak_fast_update () -function returns 0 upon successful completion.
