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);
#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 regu-
lar 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.
EAGAIN A resource control limiting the number of
tasks or LWPs in the current project or zone
has been exceeded.
