NAME
al_run_detached_thread - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro.h>
void al_run_detached_thread(void *(*proc)(void *arg), void *arg)
DESCRIPTION
Runs the passed function in its own thread, with arg passed to it as only parameter. This is similar to
calling al_create_thread(3alleg5), al_start_thread(3alleg5) and (after the thread has finished)
al_destroy_thread(3alleg5) - but you don't have the possibility of ever calling al_join_thread(3alleg5)
on the thread any longer.
