Arguments
| :: Maybe [(String, String)] | environment variables |
| -> FilePath | Filename of the executable (see |
| -> [String] | any arguments |
| -> ByteString | standard input |
| -> IO (ExitCode, ByteString, ByteString) | exitcode, stdout, stderr |
Version of readProcessWithExitCode that uses lazy bytestrings
instead of strings and allows setting environment variables.
readProcessWithExitCode creates an external process, reads its
standard output and standard error strictly, waits until the process
terminates, and then returns the ExitCode of the process,
the standard output, and the standard error.
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.
