settaskid(2)				   System Calls 			     settaskid(2)

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

       #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);

       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  set-
       taskid() 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.

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

       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.

		 A resource control on the given project would be 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.

       See attributes(5)  for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |MT-Level		     |Async-Signal-Safe 	   |
