+.SH NAME
+sched_getparam
+\(em get scheduling parameters
+(\fBREALTIME\fP)
+.SH SYNOPSIS
+.LP
+.nf
+#include <sched.h>
+.P
+int sched_getparam(pid_t \fIpid\fP, struct sched_param *\fIparam\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIsched_getparam\fR()
+function shall return the scheduling parameters of a process specified by
+.IR pid
+in the
+.BR sched_param
+structure pointed to by
+.IR param .
+.P
+If a process specified by
+.IR pid
+exists, and if the calling process has permission, the scheduling
+parameters for the process whose process ID is equal to
+.IR pid
+shall be returned.
+.P
+If
+.IR pid
+is zero, the scheduling parameters for the calling process shall be
+returned. The behavior of the
+\fIsched_getparam\fR()
+function is unspecified if the value of
+.IR pid
+is negative.
+.SH "RETURN VALUE"
+Upon successful completion, the
+\fIsched_getparam\fR()
+function shall return zero. If the call to
+\fIsched_getparam\fR()
+is unsuccessful, the function shall return a value of \-1 and set
+.IR errno
+to indicate the error.
+.SH ERRORS
+The
+\fIsched_getparam\fR()
+function shall fail if:
+.TP
+.BR EPERM
+The requesting process does not have permission to obtain the
+scheduling parameters of the specified process.
+.TP
+.BR ESRCH
+No process can be found corresponding to that specified by
+.IR pid .
