NAME
gspool_getspd - get the default permissions
SYNOPSIS
#include <gspool.h> int gspool_getspd(const int fd, struct apisphdr *res)
DESCRIPTION
The ggssppooooll__ggeettssppdd(()) function is used to retrieve the defaults
privileges, form types etc for new users on the host with which the API
is communicating.
fd is a file descriptor previously returned by gspool_open
res is a descriptor which upon return will contain the the default user
privileges. The structure apisphdr is defined in gspool.h and contains
the following elements:
- long sph_lastp
- Time last read password file
- unsigned char sph_minp
- Minimum priority
- unsigned char sph_maxp
- Maximum priority
- unsigned char sph_defp
- Default priority
- char sph_form[]
- Default form type
- char sph_formallow[]
- Allowed form type pattern
- char sph_ptr[]
- Default printer
- char sph_ptrallow[]
- Allowed printer pattern
- unsigned long sph_flgs
- Privilege flag
- classcode_t sph_class
- Class of printers
- unsigned char sph_cps
- Maximum copies allowed
- unsigned char sph_version
- Release of GNUspool
- The "spu_flgs" field will contain a combination of the following:
- PV_ADMIN
- Administrator (edit admin file)
- PV_SSTOP
- Can run sstop (can stop scheduler)
- PV_FORMS
- Can use other forms than default
- PV_CPRIO
- Can change priority on queue
- PV_OTHERJ
- Can change other users' jobs
- PV_PRINQ
- Can move to printer queue
- PV_HALTGO
- Can halt, restart printer
- PV_ANYPRIO
- Can set any priority on queue
- PV_CDEFLT
- Can change own default priority
- PV_ADDDEL
- Can add/delete printers
- PV_COVER
- Can override class
- PV_UNQUEUE
- Can unqueue jobs
- PV_VOTHERJ
- Can view other jobs not neccesarily edit
- PV_REMOTEJ
- Can access remote jobs
- PV_REMOTEP
- Can access remote printers
- PV_FREEZEOK
- Can save default options
- PV_ACCESSOK
- Can access sub-screens
- PV_OTHERP
- Can use other printers from default
- ALLPRIVS
- A combination of all of the above
RETURN VALUES
The function gspool_getspd() returns 0 if successful otherwise one of
the following codes:
- GSPOOL_UNKNOWN_USER
- Invalid user name
- 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
EXAMPLE
- An example to view the default privleges on the host machine:
- int fd, ret;
struct apisphdr res; - fd = gspool_open("myhost", (char *) 0, 0);
if (fd < 0) { /* error handling */... - }
- ret = gspool_getspd(fd, &res);
if (ret < 0) { /* error handling */... - }
- if (res.sph_flgs & PV_HALTGO)
printf("users cannot stop and start printers\n");
- printf("the default maximum priority is %s\n", res);
gspool_close(fd);
