NAME

gspool_jobupd - update the details of a job


SYNOPSIS

#include <gspool.h>

int gspool_jobupd(const int fd, const unsigned flags, const slotno_t slot, struct apispq * jobd)


DESCRIPTION

The gspool_jobupd() function is used to update the details of a job.

fd is a file descriptor previously returned by gspool_open

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

slot is the slot number corresponding to the job as previously returned by gspool_joblist or gspool_jobfindslot.

jobd is a descriptor containing the job descriptor as defined in gspool.h.

The fields in struct apispq are defined in the gspool_jobread(3) documentation.

Note that we recommend that the whole structure be first read in with gspool_jobread or gspool_jobfind and then required fields updaated; this approach will cover any future extensions with additional fields.


RETURN VALUES

The function returns 0 if successful otherwise one of the error codes listed in Chapter 3.


EXAMPLE

An example to change the name of job ``readme.txt'' to ``myfile''

 int fd, ret, nj, i;
 struct apispq job;
 slotno_t *slots;
 fd = gspool_open("myhost", (char *) 0, 0);
 if  (fd < 0) { /* error handling */
     ...
 }
 /* make a list of jobs */
 ret = gspool_joblist(fd, 0, &nj, &slots); 
 if (ret < 0) { /* error handling */
     ...
 }
 for (i = 0; i < nj; i++) {
     ret = gspool_jobread(fd, 0, list[i], &job);
     if  (ret < 0)
         continue;
     if (strcmp(job.apispq_file, "readme.txt"))
         continue;
     strcpy(job.apispq_file, "myfile");
     ret = gspool_jobupd(fd, 0, list[i], &job);
     if (ret < 0) { /* error handling */
         ...
     }
     break;
 }
 gspool_close(fd);
