Command line

commandLineToArgv :: WindowsString -> IO [WindowsString] Source #

This function can be used to parse command line arguments and return the split up arguments as elements in a list.

getCommandLineW :: IO LPWSTR Source #

getArgs :: IO [WindowsString] Source #

Based on GetCommandLineW. This behaves slightly different than getArgs. See the online documentation: https://learn.microsoft.com/en-us/windows/win32/api/processenv/nf-processenv-getcommandlinew
