.SH DESCRIPTION
The
.BR libsimple_unlist ()
function removes the
.IR i th
element from
.IR list ,
and pushes up all following elements one step, so
next element take the removed elements position. The
.I width
parameter shall be the size of each element, in bytes,
.RI ( sizeof(*list)
in all sane circumstances).
.I np
shall be a pointer to the number of elements stored in
.IR list ,
.I *np
will be set to
.IR *np-1 .
The function assumes that
.IR i<*np .
.PP
.BR LIBSIMPLE_UNLIST ()
is a macro-wrapper for the
.BR libsimple_unlist ()
function which does not have the parameter
.IR width ,
instead it is inferred from the type of
.IR list ;
as such,
.I type
must be a complete, non-void type.
.SH RETURN VALUE
None.
.SH ERRORS
The
.BR libsimple_unlist ()
and
.BR LIBSIMPLE_UNLIST ()
functions cannot fail.
