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 .sp .LP The \fBsettaskid()\fR function will fail if: .sp .ne 2 .na \fB\fBEACCES\fR\fR .ad .RS 10n The invoking task was created with the \fBTASK_FINAL\fR flag. .RE .sp .ne 2 .na \fB\fBEAGAIN\fR\fR .ad .RS 10n A resource control limiting the number of tasks or LWPs in the current project or zone has been exceeded. .sp A resource control on the given project would be exceeded. .RE .sp .ne 2 .na \fB\fBEINVAL\fR\fR .ad .RS 10n The given project \fBID\fR is not within the valid project \fBID\fR range. .RE .sp .ne 2 .na \fB\fBEPERM\fR\fR .ad .RS 10n The {\fBPRIV_PROC_TASKID\fR} privilege is not asserted in the effective set of the calling process. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
