NAME
gbatch_vardel - is used to delete a variable

SYNOPSIS
#include <gbatch.h>

int gbatch_vardel(const int fd, const unsigned flags, const slotno_t slot)

DESCRIPTION
The function gbatch_vardel() is used to delete a variable from the variable list.

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

flags is 0 or "GBATCH_FLAG_IGNORESEQ" to attempt to ignore recent changes to the variable list.

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

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

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 */
         . . .
     }
 }
