.SH DESCRIPTION
|
|
|
|
.LP
|
|
|
|
The \fIsched_rr_get_interval\fP() function shall update the \fBtimespec\fP
|
|
|
|
structure referenced by the \fIinterval\fP
|
|
|
|
argument to contain the current execution time limit (that is, time
|
|
|
|
quantum) for the process specified by \fIpid\fP. If \fIpid\fP
|
|
|
|
is zero, the current execution time limit for the calling process
|
|
|
|
shall be returned.
|
|
|
|
.SH RETURN VALUE
|
|
|
|
.LP
|
|
|
|
If successful, the \fIsched_rr_get_interval\fP() function shall return
|
|
|
|
zero. Otherwise, it shall return a value of -1 and set
|
|
|
|
\fIerrno\fP to indicate the error.
|
|
|
|
.SH ERRORS
|
|
|
|
.LP
|
|
|
|
The \fIsched_rr_get_interval\fP() function shall fail if:
|
|
|
|
.TP 7
|
|
|
|
.B ESRCH
|
|
|
|
No process can be found corresponding to that specified by \fIpid\fP.
