-.TH GET_NPROCS 3 2012-03-20 "GNU" "Linux Programmer's Manual"
-.SH NAME
-get_nprocs, get_nprocs_conf \- get number of processors
-.SH SYNOPSIS
-.B #include <sys/sysinfo.h>
-.sp
-.BI "int get_nprocs(void);"
-.br
-.BI "int get_nprocs_conf(void);"
-.SH DESCRIPTION
-The function
-.BR get_nprocs_conf ()
-returns the number of processors configured by the operating system.
-
-The function
-.BR get_nprocs ()
-returns the number of processors currently available in the system.
-This may be less than the number returned by
-.BR get_nprocs_conf ()
-because processors may be offline (e.g., on hotpluggable systems).
-.SH RETURN VALUE
-As given in DESCRIPTION.
-.SH CONFORMING TO
-These functions are GNU extensions.
-.SH NOTES
-The current
-.\" glibc 2.15
-implementation of these functions is rather expensive,
-since they open and parse files in the
-.I /sys
-filesystem each time they are called.
-
-The following
-.BR sysconf (3)
-calls make use of the functions documented on this page
-to return the same information.
-.nf
-
- np = sysconf(_SC_NPROCESSORS_CONF); /* processors configured */
- np = sysconf(_SC_NPROCESSORS_ONLN); /* processors available */
-.fi
-.SH EXAMPLE
-The following example shows how
-.BR get_nprocs ()
-and
-.BR get_nprocs_conf ()
-can be used.
-
-.nf
-#include <stdio.h>
-#include <sys/sysinfo.h>
-
-int
-main(int argc, char *argv[])
-{
- printf("This system has %d processors configured and "
- "%d processors available.\\n",
- get_nprocs_conf(), get_nprocs());
- return 0;
-}
-.fi

-.SH COLOPHON
-This page is part of release 3.79 of the Linux
-.I man-pages
-project.
