rarray_len, rarray_set_len \- get/set array length.

#include <roy.h>
.PP
unsigned int rarray_len (RArray *\fIarray\fR);
.PP
void rarray_set_len (RArray *\fIarray\fR, unsigned int \fIlen\fR);
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIrarray_len\fR\|(3) returns the number of entries in the array \fIarray\fR.
.PP
\&\fIrarray_set_len\fR\|(3) sets the number of entries in the array to
\&\fIlen\fR.  If len is greater than the current number, the current
entry is advanced to that position, but none of the entries over which
it had to skip to get there are changed.  If more blocks are required
(see \fIrarray_new\fR\|(3)), then they are created as needed.  If the rarray
is to be shrunken, the current entry pointer is merely moved back.
.SH "RETURN VALUE"
.IX Header "RETURN VALUE"
\&\fIrarray_len\fR\|(3) returns the number of entries in the array.
.PP
\&\fIrarray_set_len\fR\|(3) returns no value.
