Hi! This patch makes CPU_COUNT macro working even in C++ and as an added bonus fixes also bits/sched.h which got out of sync with linux version of this header during last change. 2007-07-17 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/bits/sched.h (__sched_cpucount): Add __BEGIN_DECLS/__END_DECLS around the prototype. * bits/sched.h (__sched_cpucount): Likewise. Make second argument pointer to const cpu_set_t. --- libc/sysdeps/unix/sysv/linux/bits/sched.h.jj 2007-06-12 14:08:19.000000000 +0200 +++ libc/sysdeps/unix/sysv/linux/bits/sched.h 2007-07-17 20:45:00.000000000 +0200 @@ -131,8 +131,14 @@ typedef struct ((cpusetp)->__bits[__CPUELT (cpu)] &= ~__CPUMASK (cpu)) # define __CPU_ISSET(cpu, cpusetp) \ (((cpusetp)->__bits[__CPUELT (cpu)] & __CPUMASK (cpu)) != 0) + +__BEGIN_DECLS + extern int __sched_cpucount (size_t __setsize, const cpu_set_t *__setp) __THROW; + +__END_DECLS + # define __CPU_COUNT(cpusetp) \ __sched_cpucount (sizeof (cpu_set_t), cpusetp) #endif --- libc/bits/sched.h.jj 2007-04-23 10:54:00.000000000 +0200 +++ libc/bits/sched.h 2007-07-17 20:46:06.000000000 +0200 @@ -68,7 +68,14 @@ typedef struct ((cpusetp)->__bits[__CPUELT (cpu)] &= ~__CPUMASK (cpu)) # define __CPU_ISSET(cpu, cpusetp) \ (((cpusetp)->__bits[__CPUELT (cpu)] & __CPUMASK (cpu)) != 0) -extern int __sched_cpucount (size_t __setsize, cpu_set_t *__setp) __THROW; + +__BEGIN_DECLS + +extern int __sched_cpucount (size_t __setsize, const cpu_set_t *__setp) + __THROW; + +__END_DECLS + # define __CPU_COUNT(cpusetp) \ __sched_cpucount (sizeof (cpu_set_t), cpusetp) #endif Jakub
