Subject: pthread.h, sys/types.h Add missing pthread methods
X-Git-Tag: newlib-snapshot-20160226~5
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=4fa84f10eca1f824649ca23cda57066bd085d4a0;p=newlib-cygwin.git

pthread.h, sys/types.h Add missing pthread methods

	* pthread.h: Add prototypes for pthread_condattr_getclock(),
	pthread_condattr_setclock(), pthread_setschedpri(),
	pthread_getcpuclockid(), pthread_getconcurrency(), and
	pthread_setconcurrency().  Also cleaned up file header to
	remove CVS Id string.
	* sys/types.h: Add clock ID to pthread_condattr_t.
