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 theappropriate 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.SunOS 5.11 Last change: 5 May 2010 1
