Corinna Vinschen ce48510394 * miscfuncs.cc (DEFAULT_STACKSIZE): Remove. 
(CygwinCreateThread): Simplify code by assuming that now stack-related
	input values are undefined.  Set stack protection to PAGE_READWRITE,
	as is default on Windows.  Add lengthy comment to explain POSIX
	guardpage.
	* thread.cc (pthread_attr::pthread_attr): Initialize stacksize as
	PTHREAD_DEFAULT_STACKSIZE.  Initialize guardsize as
	PTHREAD_DEFAULT_GUARDSIZE.
	* thread.h (PTHREAD_DEFAULT_STACKSIZE): Define.  Add comment to explain.

RLIMIT_STACK.

	* registry.cc (get_registry_hive_path): Expect the user hive path to
	be never longer than MAX_PATH.  Don't prepend native NT path prefix
	here.  Add comment.
	(load_registry_hive): Prepend native NT path prefix here.  Additionally
	try to load user's classes hive.
	* uinfo.cc (cygheap_user::env_userprofile): Reduce size of

Christopher Faylor c38a2d8373 * syscalls.cc (setsid): On second thought, in the spirit of keeping things 
kludgy, set ctty to -2 here as a special flag, and...
(open): ...only eschew setting O_NOCTTY when that case is detected.
 2012-02-10 16:43:36 +00:00

 2012-02-08 19:58:37 +00:00
Christopher Faylor 30c66cea49 * include/sys/wait.h: Remove C++ inline functions for `union wait'. For C++
