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_setschedparam.c | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 src/thread/pthread_setschedparam.c (limited to 'src/thread/pthread_setschedparam.c') diff --git a/src/thread/pthread_setschedparam.c b/src/thread/pthread_setschedparam.c new file mode 100644 index 00000000..8e8b5a19 --- /dev/null +++ b/src/thread/pthread_setschedparam.c @@ -0,0 +1,10 @@ +#include "pthread_impl.h" + +int pthread_setschedparam(pthread_t t, int policy, const struct sched_param *param) +{ + int r; + __lock(t->killlock); + r = t->dead ?
