flags is either zero, or "GSPOOL_FLAG_IGNORESEQ" to ignore changes since the list was last read.

slot is the slot number corresponding to the printer as previously returned by gspool_ptrlist, or gspool_ptrfindslot.

GSPOOL_INVALID_FD: Invalid File descriptor
GSPOOL_BADWRITE: failure writing to the network
GSPOOL_BADREAD: failure reading from the network
GSPOOL_SEQUENCE: Sequence error, slot may be out of date

EXAMPLE

An example to delete all printers:

 int fd, ret, np, i;
 slotno_t *slots;

 fd = gspool_open("myhost", (char *)0, 0);
 if (fd < 0) { /* error handling */
     ...
 }

 ret = gspool_ptrlist(fd, GSPOOL_LOCALONLY, &np, &slots);
 if (ret < 0) { /* error handling */
     ...
 }

 for (i = 0; i < np; i++) {
     ret = gspool_ptrdel(fd, 0, slots[i]);
     if (ret < 0) { /* error handling */
         ...
     }
