 .SH DESCRIPTION
 The
 .BR libkeccak_shakesum_fd ()
-function calculates a SHAKE hashsum of a file, whose file desriptor is
-specified by \fIfd\fP (and should be at the beginning of the file.)
-The hash algorithm is tuned by the \fIsemicapacity\fP and \fIoutput\fP
-parameters; they specify the half of the capacity and the output size,
-respectively, in bits.
