Process module:System -package:unix -is:module -package:cryptonite -package:process

A running process. The three type parameters provide the type of the standard input, standard output, and standard error streams. To interact with a Process use the functions from the section Interact with a process.
Process a list of flags (usually obtained from getArgs/expandArgsAt) with a mode. Returns Left and an error message if the command line fails to parse, or Right and the associated value.
ProcessId, number of threads, parent ProcessId, process base priority, path of executable file
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.
An abstract configuration for a process, which can then be launched into an actual running Process. Takes three type parameters, providing the types of standard input, standard output, and standard error, respectively. There are three ways to construct a value of this type:
  • With the proc smart constructor, which takes a command name and a list of arguments.
  • With the shell smart constructor, which takes a shell string
  • With the IsString instance via OverloadedStrings. If you provide it a string with no spaces (e.g., "date"), it will treat it as a raw command with no arguments (e.g., proc "date" []). If it has spaces, it will use shell.
In all cases, the default for all three streams is to inherit the streams from the parent process. For other settings, see the setters below for default values. Once you have a ProcessConfig you can launch a process from it using the functions in the section Launch a process.
This will always come first, before any output or exit code.

A convenient handler for the output of a createProcess call. This data containes 4 components:
