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 documentation for gspool_jobread(3).

       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 gspool_jobupd() returns 0 if successful, otherwise one of the following
       codes:

       GSPOOL_BAD_PRIORITY
               The job's priority is outside the range for the user, or it cannot be changed by
               the user.

       GSPOOL_INVALID_FD
               Invalid File descriptor

       GSPOOL_BADWRITE
               failure writing to the network

       GSPOOL_BADREAD
               failure reading from the network

       GSPOOL_NOPERM
               The user does not have permission

       GSPOOL_ZERO_CLASS
               A class code of zero is illegal

       GSPOOL_BAD_COPIES
               The copies field is outside the limit for the user

       GSPOOL_BAD_FORM
               The form type filed has been left empty

       GSPOOL_SEQUENCE
               Sequence error, slot may be out of date

       GSPOOL_UNKNOWN_JOB
               Job not found

       GSPOOL_INVALIDSLOT
               Invalid slot number

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);
