From 1e21e78bf7a5c24c217446d8760be7b7188711c2 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sun, 11 Nov 2012 15:38:04 -0500 Subject: add support for thread scheduling (POSIX TPS option) linux's sched_* syscalls actually implement the TPS (thread scheduling) functionality, not the PS (process scheduling) functionality which the sched_* functions are supposed to have. omitting support for the PS option (and having the sched_* interfaces fail with ENOSYS rather than omitting them, since some broken software assumes they exist) seems to be the only conforming way to do this on linux. --- src/thread/pthread_attr_setscope.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'src/thread/pthread_attr_setscope.c') diff --git a/src/thread/pthread_attr_setscope.c b/src/thread/pthread_attr_setscope.c index d56ee391..46b520c0 100644 --- a/src/thread/pthread_attr_setscope.c +++ b/src/thread/pthread_attr_setscope.c @@ -2,6 +2,12 @@ int pthread_attr_setscope(pthread_attr_t *a, int scope) { - if (scope > 1U) return EINVAL; - return 0; + switch (scope) { + case PTHREAD_SCOPE_SYSTEM: + return 0; + case PTHREAD_SCOPE_PROCESS: + return ENOTSUP; + default: + return EINVAL; + } } -- cgit v1.2.1
