Redirect outputdebugstring to file

There is also an option for writing a textfile for each subprocess that strace sees. There's also the method of named pipes. I recommend reading the linked post about the dialog command for thorough description of what's happening.

So hashdeep -rXvvl -j 30 -k checksums. Hence, file descriptor 1 will continue using the same underlying Win32 handle as before, and sending output to cout will not produce the desired effect.

Each process is allowed only one console, so calling AllocConsole multiple times will not produce multiple consoles. The code is wrapped in preprocessor conditionals to allow it to be easily compiled out for release applications. The code in test.

Additionally, if you are using STL streams it tests the wide character versions of cin , cout , cerr , and clog. Since Win32 destroys the console when the application exits, I pause for two seconds before exiting so that you can see the last few pieces of output. Overall, having a console associated with a Win32 GUI application is a very useful tool.

Another application might be to use the console as a simple debugger that allows you to print out crucial data structures and inspect and change variables without the use of a full-blown interactive debugger. The text was updated successfully, but these errors were encountered:. The protocol and kernel objects used are listed in the link above. If multiple threads are outputting debug statements, the mutex may introduce a timing effect on the running application and may mask timing issues when used.

Sorry, something went wrong. Lines to in 9b14bbd. Looking at the reference code I believe thread::spawn is the function to spawn a thread. Should we allow for redirecting to a log file in addition to OutputDebugString.

I have determined that crate winapi does not seem to contain the following win32 APIs. If not, if those APIs are part of the statically linked libraries, you could try this:. The standard library's thread::spawn is the way to go. The code I linked earlier uses that. In a UWP window based application printf - even with fflush - does not cause the read to unblock.

I suspect there is additional buffering in play. Josh, Thanks for reviewing my comments. I saw that stackoverflow article too. Here is what I know regarding buffering on Windows and on the servo rust code so far.

Alternatively, you can use setbuf stdout, NULL and you don't have to perform a fflush. When either is done, the thread performing the read function call returns. However, all write 1, "output to stdout.
