setting processor affinity

[mhjamal]

hi

I am using the sched_setaffinity function to allot each thread to specific processor. I am getting the following warning.

"implicit decelaration of function 'sched_setaffinity'

I have included the "sched.h" header file. I am using Linux red hat 4 enterprise AS and gcc 3.4.6.

How can i overcome this warning.
Is there any external library for this like -lpthread and -lm.

Can anyone help me on this
Thanks

0) RTFM
1) Probably you need to include sched the following way:
#define _GNU_SOURCE
#include <sched.h>
2) This function might no be supported on your system, check its man page (or google for it) for versions of kernel and glibc from which it is supported.
