Project(3PERL) Perl Library Functions Project(3PERL)NAMEProject - Perl interface to Projects
SYNOPSIS
use Sun::Solaris::Project qw(:ALL);
my $projid = getprojid();
DESCRIPTION
This module provides wrappers for the Project-related system calls and
the libproject(3LIB) library. Also provided are constants from the var‐
ious Project-related headers.
Constants
MAXPROJID, PROJNAME_MAX, PROJF_PATH, PROJECT_BUFSZ, SETPROJ_ERR_TASK,
and SETPROJ_ERR_POOL.
Functions
getprojid()
This function returns the numeric project ID of the calling process
or undef if the underlying getprojid(2) system call is unsuccess‐
ful.
setproject($project, $user, $flags)
If $user is a member of the project specified by $project, setpro‐
ject() creates a new task and associates the appropriate resource
controls with the process, task, and project. This function returns
0 on success. If the underlying task creation fails, SET‐
PROJ_ERR_TASK is returned. If pool assignment fails, SET‐
PROJ_ERR_POOL is returned. If any resource attribute assignments
fail, an integer value corresponding to the offset of the failed
attribute assignment in the project database is returned. See set‐
project(3PROJECT).
activeprojects()
This function returns a list of the currently active projects on
the system. Each value in the list is the numeric ID of a currently
active project.
getprojent()
This function returns the next entry from the project database.
When called in a scalar context, getprojent() returns only the name
of the project. When called in a list context, getprojent() returns
a 6-element list consisting of:
($name, $projid, $comment, \@users, \@groups, $attr)
\@users and \@groups are returned as arrays containing the appro‐
priate user or project lists. On end-of-file undef is returned.
setprojent()
This function rewinds the project database to the beginning of the
file.
endprojent()
This function closes the project database.
getprojbyname($name)
This function searches the project database for an entry with the
specified nam. It returns a 6-element list as returned by getpro‐
jent() if the entry is found and undef if it cannot be found.
getprojbyid($id)
This function searches the project database for an entry with the
specified ID. It returns a 6-element list as returned by getpro‐
jent() if the entry is found or undef if it cannot be found.
getdefaultproj($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.
Object methods
None.
