# 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 */
             . . .
         }
     }
