SCHED_GETCPU(3)            Linux Programmer's Manual           SCHED_GETCPU(3)



 

NAME


       sched_getcpu - determine CPU on which the calling thread is running

 

SYNOPSIS


       #define _GNU_SOURCE
       #include 

       int sched_getcpu(void);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       sched_getcpu(): _BSD_SOURCE || _SVID_SOURCE

 

DESCRIPTION






       sched_getcpu()  returns  the  number  of  the  CPU on which the calling
       thread is currently executing.

 

RETURN VALUE


       On success, sched_getcpu()  returns  a  non-negative  CPU  number.   On
       error, -1 is returned and errno is set to indicate the error.

 

ERRORS


       ENOSYS This kernel does not implement getcpu(2).

 

VERSIONS


       This function is available since glibc 2.6.

 

CONFORMING TO


       sched_getcpu() is glibc specific.

 

NOTES


       The call

           cpu = sched_getcpu();

       is equivalent to the following getcpu(2) call:

           int c, s;
           s = getcpu(&c, NULL, NULL);
           cpu = (s == -1) ? s : c;
