The message specified by the \fImsg\fP +parameter with the byte-size specified by the \fImsglen\fP +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. On error, +-1 is returned and \fIerrno\fP is set to describe the error. +.SH ERRORS +The +.BR libkeccak_fast_update () +function may fail for any reason specified by the function +.BR realloc (3). +.SH Notes +Neither parameter by be \fINULL\fP or 0. +.SH SEE ALSO +.BR libkeccak_state_initialise (3), +.BR libkeccak_update (3), +.BR libkeccak_fast_digest (3), +.BR libkeccak_digest (3) +.SH AUTHORS +Principal author, Mattias Andrée.
