Console mode

getConsoleMode :: HANDLE -> IO DWORD Source #

setConsoleMode :: HANDLE -> DWORD -> IO () Source #

eNABLE_ECHO_INPUT :: DWORD Source #

Console code pages

Ctrl events

type CtrlEvent = DWORD Source #

cTRL_C_EVENT :: CtrlEvent Source #

cTRL_BREAK_EVENT :: CtrlEvent Source #

generateConsoleCtrlEvent :: CtrlEvent -> DWORD -> IO () Source #

Command line

commandLineToArgv :: String -> IO [String] 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 [String] 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
