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limit for the user GSPOOL_BAD_FORM The form type filed has been left empty GSPOOL_SEQUENCE Sequence error, slot may be out of date GSPOOL_UNKNOWN_JOB Job not found GSPOOL_INVALIDSLOT Invalid slot number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);
