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_getschedparam.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 src/thread/pthread_getschedparam.c (limited to 'src/thread/pthread_getschedparam.c') diff --git a/src/thread/pthread_getschedparam.c b/src/thread/pthread_getschedparam.c new file mode 100644 index 00000000..7b6a95f1 --- /dev/null +++ b/src/thread/pthread_getschedparam.c @@ -0,0 +1,17 @@ +#include "pthread_impl.h" + +int pthread_getschedparam(pthread_t t, int *restrict policy, struct sched_param *restrict param) +{ + int r; + __lock(t->killlock); + if (t->dead) { + r = ESRCH; + } else { + r = -__syscall(SYS_sched_getparam, t->tid, ¶m); + if (!r) { + *policy = __syscall(SYS_sched_getscheduler, t->tid); + } + } + __unlock(t->killlock); + return r; +} -- cgit 1.4.1
