Synopsis
- pipeProcess :: Maybe [(String, String)] -> FilePath -> [String] -> ByteString -> IO (ExitCode, ByteString)
Documentation
Arguments
| :: Maybe [(String, String)] | environment variables |
| -> FilePath | Filename of the executable (see |
| -> [String] | any arguments |
| -> ByteString | standard input |
| -> IO (ExitCode, ByteString) | exitcode, stdout |
Version of readProcessWithExitCode that uses lazy bytestrings
instead of strings and allows setting environment variables.
readProcessWithExitCode creates an external process, reads its
standard output strictly, waits until the process
terminates, and then returns the ExitCode of the process
and the standard output. stderr is inherited from the parent.
If an asynchronous exception is thrown to the thread executing
readProcessWithExitCode, the forked process will be terminated and
readProcessWithExitCode will wait (block) until the process has been
terminated.
This function was adapted from readProcessWithExitCode of module
System.Process, package process-1.6.3.0. The original code is BSD
