A Garry's Mod module to create asynchronous child processes. It also allows you to use its error, input and output handles to retrieve or push data to the process.
The only supported compilation platform for this project on Windows is Visual Studio 2017. However, it's possible it'll work with Visual Studio 2015 and Visual Studio 2019 because of the unified runtime.
On Linux, everything should work fine as is.
For macOS, any Xcode (using the GCC compiler) version MIGHT work as long as the Mac OSX 10.7 SDK is used.
These restrictions are not random; they exist because of ABI compatibility reasons.
If stuff starts erroring or fails to work, be sure to check the correct line endings (\n and such) are present in the files for each OS.
This project requires garrysmod_common, a framework to facilitate the creation of compilations files (Visual Studio, make, XCode, etc). Simply set the environment variable 'GARRYSMOD_COMMON' or the premake option 'gmcommon' to the path of your local copy of garrysmod_common.
