NAME

       settaskid, gettaskid, getprojid - set or get task or project IDs

SYNOPSIS

       #include <sys/types.h>
       #include <sys/task.h>
       #include <unistd.h>

       taskid_t settaskid(projid_t project, int flags);

       taskid_t gettaskid(void);

       #include <sys/types.h>
       #include <sys/task.h>
       #include <unistd.h>
       #include <project.h>

       projid_t getprojid(void);

DESCRIPTION

       The  settaskid()  function makes a request of the system to assign a new task ID to the calling process, changing the associated project ID
       to that specified. The calling process must have sufficient privileges to perform this operation.  The  flags  argument  should  be  either
       TASK_NORMAL for a regular task, or TASK_FINAL, which disallows subsequent settaskid() calls by the created task.

       The gettaskid() function returns the task ID of the calling process.

       The getprojid() function returns the project ID of the calling process.

RETURN VALUES

       Upon  successful completion, these functions return the appropriate task or project ID. Otherwise, -1 is returned and errno is set to indi-
       cate the error.

ERRORS

       The settaskid() function will fail if:

       EACCES          The invoking task was created with the TASK_FINAL flag.

       EAGAIN          A resource control limiting the number of tasks or LWPs in the current project or zone has been exceeded.

       EINVAL          The given project ID is not within the valid project ID range.

       EPERM           The {PRIV_PROC_TASKID} privilege is not asserted in the effective set of the calling process.
