pub unsafe extern "C" fn SDL_WaitProcess(

    block: bool,
    exitcode: *mut i32,
) -> bool
Available on crate feature dep_sdl3 only.
Expand description

Wait for a process to finish.

This can be called multiple times to get the status of a process.

The exit code will be the exit code of the process if it terminates normally, a negative signal if it terminated due to a signal, or -255 otherwise. It will not be changed if the process is still running.

If you create a process with standard output piped to the application (pipe_stdio being true) then you should read all of the process output before calling SDL_WaitProcess(). If you don’t do this the process might be blocked indefinitely waiting for output to be read and SDL_WaitProcess() will never return true;

§Parameters

  • process: The process to wait for.
  • block: If true, block until the process finishes; otherwise, report on the process’ status.
  • exitcode: a pointer filled in with the process exit code if the process has exited, may be NULL.

§Return value

Returns true if the process exited, false otherwise.

§Thread safety

This function is not thread safe.

§Availability

This function is available since SDL 3.2.0.
