module System.Process
process
Operations for creating and interacting with sub-processes.
module System.IO.Streams.Process
io-streams
A module adapting the functions from System.Process to work with io-streams.
module Streamly.Internal.System.Process
streamly-process
module Streamly.System.Process
streamly-process
Use OS processes just like native Haskell functions - to generate, transform or consume streams. See Streamly.System.Command module for a higher level wrapper over this module. See also: Streamly.Internal.System.Process for unreleased functions.

data ProcessHandle
process System.Process System.Process.Internals
A handle to a process, which can be used to wait for termination of the process using waitForProcess. None of the process-creation functions in this library wait for termination: they all return a ProcessHandle which may be used to wait for the process later. On Windows a second wait method can be used to block for event completion. This requires two handles. A process job handle and a events handle to monitor.

process System.Process.Internals
data ProcessHandle__
process System.Process.Internals
data ProcessorOption
cryptonite Crypto.System.CPU, crypton Crypto.System.CPU
CPU options impacting cryptography implementation and library performance.
ProcessCPUTime :: Clock
clock System.Clock System.Clock.Seconds
The identifier of the CPU-time clock associated with the calling process. For this clock, the value returned by getTime represents the amount of execution time of the current process.
data ProcessHandle
io-streams System.IO.Streams.Process
ProcessInput :: TerminalMode
posix-pty System.Posix.Pty
ProcessOutput :: TerminalMode
posix-pty System.Posix.Pty
newtype ProcessFailure
streamly-process Streamly.Internal.System.Process Streamly.System.Command Streamly.System.Process
An exception that is raised when a process fails.
ProcessFailure :: Int -> ProcessFailure
streamly-process Streamly.Internal.System.Process Streamly.System.Command Streamly.System.Process
The exit code of the process.
processorOptions :: [ProcessorOption]
cryptonite Crypto.System.CPU, crypton Crypto.System.CPU
Options which have been enabled at compile time and are supported by the current CPU.
processID :: PipeHandle -> ProcessID
MissingH System.Cmd.Utils
processBytes :: (MonadCatch m, MonadAsync m) => FilePath -> [String] -> Stream m Word8 -> Stream m Word8

Deprecated: Please use pipeBytes instead.
processChunks :: (MonadCatch m, MonadAsync m) => FilePath -> [String] -> Stream m (Array Word8) -> Stream m (Array Word8)
streamly-process Streamly.Internal.System.Process Streamly.System.Process

data CreateProcess
process System.Process
CreateProcess :: CmdSpec -> Maybe FilePath -> Maybe [(String, String)] -> StdStream -> StdStream -> StdStream -> Bool -> Bool -> Bool -> Bool -> Bool -> Bool -> Maybe GroupID -> Maybe UserID -> Bool -> CreateProcess
process System.Process
callProcess :: FilePath -> [String] -> IO ()
process System.Process
Creates a new process to run the specified command with the given arguments, and wait for it to finish. If the command returns a non-zero exit code, an exception is raised. If an asynchronous exception is thrown to the thread executing callProcess, the forked process will be terminated and callProcess will wait (block) until the process has been terminated.
cleanupProcess :: (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle) -> IO ()
process System.Process
Cleans up the process. This function is meant to be invoked from any application level cleanup handler. It terminates the process, and closes any CreatePipe handles.
