Operations for creating and interacting with sub-processes.
A collection of FFI declarations for interfacing with Win32.
A module adapting the functions from System.Process to work with io-streams.
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.
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.
CPU options impacting cryptography implementation and library performance.
ProcessId, number of threads, parent ProcessId, process base priority, path of executable file
This will always come first, before any output or exit code.
