TProcess.WaitOnExit function

Member of TProcesspublicIn unit Process

Wait for the program to stop executing.

Declaration

pascal
function WaitOnExit: Boolean
function WaitOnExit(Timeout: DWord): Boolean

Arguments

Timeout

Timeout for wait (in milliseconds).

Function result

True means the process was successfully waited on, False indicates some error occurred.

Description

WaitOnExit waits for the running program to exit. It returns True if the wait was successful, or False if there was some error waiting for the program to exit.

Note that the return value of this function has changed. The old return value was a DWord with a platform dependent error code. To make things consistent and cross-platform, a boolean return type was used.

The TimeOut argument can be used to specify a timeout in milliseconds. If omitted, the call will wait indefinitely.

Errors

On error, False is returned. No extended error information is available, as it is highly system dependent.
