Struct `std.process.Config`

Options that control the behaviour of process creation functions in this module. Most options only apply to spawnProcess and spawnShell.


						
				struct Config
				;

Fields

Name	Type	Description
`flags`	`Config.Flags`	Flag options. Use bitwise OR to combine flags.
`preExecDelegate`	`nothrow @nogc @safe bool delegate()`	A delegate that is called before `exec` in `spawnProcess`. It returns `true` if succeeded and otherwise returns `false`.
`preExecFunction`	`nothrow @nogc @safe bool function()`	A function that is called before `exec` in `spawnProcess`. It returns `true` if succeeded and otherwise returns `false`.

Methods

Name	Description
`opBinary` (other)	For backwards compatibility, and cases when only flags need to be specified in the `Config`, these allow building `Config` instances using flag names only.
`opOpAssign` (other)	For backwards compatibility, and cases when only flags need to be specified in the `Config`, these allow building `Config` instances using flag names only.
`opUnary` ()	For backwards compatibility, and cases when only flags need to be specified in the `Config`, these allow building `Config` instances using flag names only.

Enums

Name	Description
`Flags`	Flag options. Use bitwise OR to combine flags.

Example

auto logFile = File("myapp_error.log", "w");

// Start program, suppressing the console window (Windows only),
// redirect its error stream to logFile, and leave logFile open
// in the parent process as well.
auto pid = spawnProcess("myapp", stdin, stdout, logFile,
                        Config.retainStderr | Config.suppressConsole);
scope(exit)
{
    auto exitCode = wait(pid);
    logFile.writeln("myapp exited with code ", exitCode);
    logFile.close();
}
