Subject: [PATCH 02/10] Only ignore expected Cygwin OutputDebugStrings()
|
|
|
|
Rather than ignoring all debug strings starting with 'cYg', just ignore
|
|
the expected ones:
|
|
|
|
- 'cYgSiGw00f' informs the debugger of a Cygwin signal in the debuggee
|
|
- 'cYgstd' invites the debugger to alter stdin/out/err fds in the debuggee
|
|
- 'cYgFFFFFFFFFF' invites the debugger to activate strace output from the debugee
|
|
|
|
Any other debug string starting 'cYg' is unexpected, and reported
|
|
verbatim.
