.SH DESCRIPTION
.sp
.LP
The \fBsettaskid()\fR function makes a request of the system to assign a new task \fBID\fR to the calling process, changing the associated project \fBID\fR to that specified. The calling process must have sufficient privileges to perform this operation. The \fIflags\fR argument should be either \fBTASK_NORMAL\fR for a regular task, or \fBTASK_FINAL\fR, which disallows subsequent \fBsettaskid()\fR calls by the created task.
.sp
.LP
The \fBgettaskid()\fR function returns the task \fBID\fR of the calling process.
.sp
.LP
The \fBgetprojid()\fR function returns the project \fBID\fR of the calling process.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, these functions return the appropriate task or project \fBID\fR. Otherwise, \(mi1 is returned and \fBerrno\fR is set to indicate the error.
.SH ERRORS
