Project

- Perl interface to Projects

Synopsis

use Sun::Solaris::Project qw(:ALL);
my $projid = getprojid();

Description

This module provides wrappers for the Project-related system calls and the libproject(3LIB) library. Also provided are constants from the various Project-related headers.

Constants

MAXPROJID, PROJNAME_MAX, PROJF_PATH, PROJECT_BUFSZ, SETPROJ_ERR_TASK, and SETPROJ_ERR_POOL.

Functions

getprojid()

This function returns the numeric project ID of the calling process or undef if the underlying getprojid(2) system call is unsuccessful.

setproject($project, $user, $flags)

If $user is a member of the project specified by $project, setproject() creates a new task and associates the appropriate resource controls with the process, task, and project. This function returns 0 on success. If the underlying task creation fails, SETPROJ_ERR_TASK is returned. If pool assignment fails, SETPROJ_ERR_POOL is returned. If any resource attribute assignments fail, an integer value corresponding to the offset of the failed attribute assignment in the project database is returned. See setproject(3PROJECT).

activeprojects()

This function returns a list of the currently active projects on the system. Each value in the list is the numeric ID of a currently active project.

getprojent()

This function returns the next entry from the project database. When called in a scalar context, getprojent() returns only the name of the project. When called in a list context, getprojent() returns a 6-element list consisting of:

($name, $projid, $comment, \@users, \@groups, $attr)

\@users and \@groups are returned as arrays containing the appropriate user or project lists. On end-of-file undef is returned.

setprojent()

This function rewinds the project database to the beginning of the file.

endprojent()

This function closes the project database.

getprojbyname($name)

This function searches the project database for an entry with the specified nam. It returns a 6-element list as returned by getprojent() if the entry is found and undef if it cannot be found.

getprojbyid($id)

This function searches the project database for an entry with the specified ID. It returns a 6-element list as returned by getprojent() if the entry is found or undef if it cannot be found.

getdefaultproj($user)

This function returns the default project entry for the specified user in the same format as getprojent(). It returns undef if the user cannot be found. See getdefaultproj(3PROJECT) for information about the lookup process.

fgetprojent($filehandle)

This function returns the next project entry from $filehandle, a Perl file handle that must refer to a previously opened file in project(4) format. Return values are the same as for getprojent().

inproj($user, $project)

This function checks whether the specified user is able to use the project. This function returns true if the user can use the project and false otherwise. See inproj(3PROJECT).

getprojidbyname($project)

This function searches the project database for the specified project. It returns the project ID if the project is found and undef if it is not found.

Class methods

None.
