 .SH DESCRIPTION
 The
 .BR libkeccak_fast_digest ()
 function absorbs the last part of (or all of) a message,
 and returns the hash of the entire message. The last part
-of the message is specified by the \fImsg\fP parameter, and
-its byte-size is specified by the \fImsglen\fP parameter. If
-all of the message has already be processed by calls to the
+of the message is specified by the
+.I msg
+parameter, and its byte-size is specified by the
+.I msglen
+parameter. If all of the message has already be processed
+by calls to the
 .BR libkeccak_update (3)
 function or the
 .BR libkeccak_fast_update (3)
-function (with the same pointer on \fIstate\fP,) \fImsg\fP
-and \fImsglen\fP should be set to \fINULL\fP and 0, respectively.

 If the message is not comprised a whole number of bytes,
 the number of bits, modulus 8, in the message should be

 .PP
-\fIsuffix\fP should be a NUL-terminated string of ASCII '1':s
-and '0':s, representing the bits that should be appended to
-the message. If this string is empty, \fINULL\fP may be used
-instead. This is used to select hash algorithm. For pure Keccak,
-\fINULL\fP or "" is used. For the other algorithms the constants
-\fBLIBKECCAK_SHA3_SUFFIX\fP (for SHA-3),
-\fBLIBKECCAK_RAWSHAKE_SUFFIX\fP (for RawSHAKE), and
-\fBLIBKECCAK_SHAKE_SUFFIX\fP (for SHAKE) are used.

-The hash of the message will be stored to \fIhashsum\fP,

-performance of the call.) A total of ((\fIstate->n\fP + 7) / 8)

-Therefore, \fIhashsum\fP needs at least an allocation size
