I<slot>B<)>

=head1 DESCRIPTION

The function B<gbatch_vardel()> is used to delete a variable from the variable list.

I<fd> is a file descriptor which was previously returned by a
successful call to gbatch_open(3).

I<flags> is 0 or C<GBATCH_FLAG_IGNORESEQ> to attempt to ignore recent
changes to the variable list.

I<slot> is the slot number corresponding to the variable as returned
by gbatch_varlist(3) or xb_varfindslot(3).

=head1 RETURN VALUES

The function returns 0 if successful, otherwise an error code as
defined in the include file \fBgbatch.h\fR.

=head1 EXAMPLE

This example deletes all the variables owned by the user.

 int fd, ret, cnt;
 int numvars;
 slotno_t *list;

 fd = gbatch_open("myhost", (char *)0);
 ret = gbatch_varlist(fd, GBATCH_FLAG_USERONLY, &numvars, &list);
 if (fd < 0)  { /* process error */
     . . .
 }

 for (cnt = 0; cnt < numvars, cnt++) {
     if  ((ret = gbatch_vardel(fd, 0, list[cnt])) < 0)   {
         /* process error */
         . . .
     }
 }
