(pthread_attr_getaffinity_np): Likewise. (pthread_setaffinity_np): Likewise. (pthread_getaffinity_np): Likewise. (pthread_getattr_np): Add for GNU/Linux compatibility. * libc/include/sys/types.h: Add cpuset to pthread_attr_t for RTEMS. * libc/include/sys/cdefs.h (_GNU_SOURCE): Defining _GNU_SOURCE turns on all _XXX_VISBLE feature flags. --- newlib/libc/include/pthread.h | 26 +++++++++++++++++++++++++- 1 file changed, 25 insertions(+), 1 deletion(-) (limited to 'newlib/libc/include/pthread.h') diff --git a/newlib/libc/include/pthread.h b/newlib/libc/include/pthread.h index ff7f354fd..935de4119 100644 --- a/newlib/libc/include/pthread.h +++ b/newlib/libc/include/pthread.h @@ -2,7 +2,7 @@ * * Written by Joel Sherrill . * - * COPYRIGHT (c) 1989-2010. + * COPYRIGHT (c) 1989-2013. * On-Line Applications Research Corporation (OAR). * * Permission to use, copy, modify, and distribute this software for any @@ -32,6 +32,7 @@ extern "C" { #include #include #include +#include /* Register Fork Handlers */ int _EXFUN(pthread_atfork,(void (*prepare)(void), void (*parent)(void), @@ -206,6 +207,29 @@ int _EXFUN(pthread_attr_getguardsize, int _EXFUN(pthread_attr_setguardsize, (pthread_attr_t *__attr, size_t __guardsize)); +/* POSIX thread APIs beyond the POSIX standard but provided + * in GNU/Linux.
