NAME

SDL_WaitProcess - Wait for a process to finish.

HEADER FILE

Defined in SDL3/SDL_process.h

SYNOPSIS

#include "SDL3/SDL.h"

bool SDL_WaitProcess(SDL_Process *process, bool block, int *exitcode);

DESCRIPTION

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;

FUNCTION 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.
