    Command:

    get_nprocs_conf

    
    
    

    SYNOPSIS

           #include <sys/sysinfo.h>
    
           int get_nprocs(void);
           int get_nprocs_conf(void);
    
    
    

    DESCRIPTION

           The function get_nprocs_conf() returns the number of processors config-
           ured by the operating system.
    
           The function get_nprocs() returns the number  of  processors  currently
           available  in the system.  This may be less than the number returned by
           get_nprocs_conf() because processors may be offline (e.g., on  hotplug-
           gable systems).
    
    
    

    RETURN VALUE

           As given in DESCRIPTION.
    
    
    

    CONFORMING TO

           These functions are GNU extensions.
    
    
    

    NOTES

           The  current  implementation  of  these  functions is rather expensive,
           since they open and parse files in the /sys filesystem each  time  they
           are called.
    
           The  following sysconf(3) calls make use of the functions documented on
           this page to return the same information.
    
               np = sysconf(_SC_NPROCESSORS_CONF);     /* processors configured */
               np = sysconf(_SC_NPROCESSORS_ONLN);     /* processors available */
    
    
    

    EXAMPLE

           The following example shows how get_nprocs() and get_nprocs_conf()  can
           be used.
    
           #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;
           }
