+.SH NAME
+getrusage
+\(em get information about resource utilization
+.SH SYNOPSIS
+.LP
+.nf
+#include <sys/resource.h>
+.P
+int getrusage(int \fIwho\fP, struct rusage *\fIr_usage\fP);
+.fi
+.SH DESCRIPTION
+The
+\fIgetrusage\fR()
+function shall provide measures of the resources used by the current
+process or its terminated and waited-for child processes. If the value
+of the
+.IR who
+argument is RUSAGE_SELF, information shall be returned about resources
+used by the current process. If the value of the
+.IR who
+argument is RUSAGE_CHILDREN,
+information shall be returned about resources used by the terminated and
+waited-for children of the current process. If the child is never
+waited for (for example, if the parent has SA_NOCLDWAIT set or sets
+SIGCHLD to SIG_IGN), the resource
+information for the child process is discarded and not included in the
+resource information provided by
+\fIgetrusage\fR().
+.P
+The
+.IR r_usage
+argument is a pointer to an object of type
+.BR "struct rusage"
+in which the returned information is stored.
+.SH "RETURN VALUE"
+Upon successful completion,
+\fIgetrusage\fR()
+shall return 0; otherwise, \-1 shall be returned and
+.IR errno
+set to indicate the error.
+.SH ERRORS
+The
+\fIgetrusage\fR()
+function shall fail if:
+.TP
+.BR EINVAL
+The value of the
+.IR who
+argument is not valid.
+.LP
