System Callssettaskid(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 process must have superuser 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 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.
