Christopher Faylor 44e1d662cb * strace.cc (proc_child): Don't right-shift exit value.
(main): Call ExitProcess() to exit exactly the same way as any straced child.
2012-01-31 18:06:51 +00:00
Christopher Faylor 1b23b30b29 Clean up whitespace. 2011-12-17 23:39:47 +00:00
Christopher Faylor 505bce274f * strace.cc (attach_process): Use NT_SUCCESS to figure out if
NtSetInformationProcess succeeded.
(handle_output_debug_string): Put back DebugActiveProcess since it seems to
still be needed (on my system at least).  Detect new format
_STRACE_INTERFACE_ACTIVATE_ADDR which informs whether this is a forked process
or not.  Use that to decide if forkdebug should be handled.
2011-11-24 21:54:41 +00:00
Christopher Faylor 07e7349db2 * strace.cc (handle_output_debug_string): Disable code which attempted to add
stuff in between '****' blocks since they no longer are the first thing output
by an straced process.

Corinna Vinschen 92b499acff * Align usage output, version output, as well as usage and version
option handling to use the same style throughout all Cygwin utils.

	sections for getconf, ldd, and setmetamode.

	attach for debugging when a child process starts
	* Makefile.in (strace.exe): Link with ntdll
2011-09-15 16:49:51 +00:00
