System Calls                                         settaskid(2)

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);

     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  pro-
     cess  must  have superuser privileges to perform this opera-
     tion.  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  cal-
     ling process.

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

ERRORS
     The settaskid() function will fail if:

     EACCES
           The invoking task  was  created  with  the  TASK_FINAL
           flag.

     EPERM The effective user  of  the  calling  process  is  not
           superuser.

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