.TH sched_rr_get_interval 3C "1 Apr 2008" "SunOS 5.11" "Standard C Library Functions"
.SH NAME
sched_rr_get_interval \- get execution time limits
.SH SYNOPSIS
.LP
.nf
#include <sched.h>

\fBint\fR \fBsched_rr_get_interval\fR(\fBpid_t\fR \fIpid\fR,
     \fBstruct timespec *\fR\fIinterval\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBsched_rr_get_interval()\fR function updates the \fBtimespec\fR structure referenced by the \fIinterval\fR argument to contain the current execution time limit (that is, time quantum) for the process specified by \fIpid\fR. If \fIpid\fR is 0, the current execution time limit for the calling process will be returned.
.SH RETURN VALUES
.sp
.LP
If successful, the \fBsched_rr_get_interval()\fR function returns \fB0\fR. Otherwise, it returns \fB\(mi1\fR and sets \fBerrno\fR to indicate the error.
.SH ERRORS
.sp
.LP
The  \fBsched_rr_get_interval()\fR function will fail if:
.sp
.ne 2
.mk
.na
\fB\fBESRCH\fR\fR
.ad
.RS 9n
.rt  
No process can be found corresponding to that specified by \fIpid\fR.
