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 */...} - }
gspool_close(fd);
