2018-09-12	split internal lock API out of libc.h, creating lock.h	Rich Felker	-0/+1
	this further reduces the number of source files which need to include libc.h and thereby be potentially exposed to libc global state and internals. this will also facilitate further improvements like adding an inline fast-path, if we want to do so later.
2018-05-05	improve pthread_exit synchronization with functions targeting tid	Rich Felker	-1/+1
	if the last thread exited via pthread_exit, the logic that marked it dead did not account for the possibility of it targeting itself via atexit handlers. for example, an atexit handler calling pthread_kill(pthread_self(), SIGKILL) would return success (previously, ESRCH) rather than causing termination via the signal. move the release of killlock after the determination is made whether the exiting thread is the last thread. in the case where it's not, move the release all the way to the end of the function. this way we can clear the tid rather than spending storage on a dedicated dead-flag. clearing the tid is also preferable in that it hardens against inadvertent use of the value after the thread has terminated but before it is joined.
2018-01-09	consistently use the LOCK an UNLOCK macros	Jens Gustedt	-2/+2
	In some places there has been a direct usage of the functions. Use the macros consistently everywhere, such that it might be easier later on to capture the fast path directly inside the macro and only have the call overhead on the slow path.
2013-06-26	fix failure of pthread_setschedparam to pass correct param to kernel	Rich Felker	-1/+1
	the address of the pointer, rather than the pointer, was being passed. this was probably a copy-and-paste error from corresponding get code.
2012-11-11	add support for thread scheduling (POSIX TPS option)	Rich Felker	-0/+10
	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.
