Hi all, I'm looking for a reviewer of attached patch and I'm also hoping someone has a scanner who's driver uses threads can test this patch to verify no regressions occurred (be sure and use --enable-pthread on configure).
Current code assumes/requires that SANE_Pid is represented as an integer on all platforms because we do "pid == -1" checks everywhere. Pthreads says that it can not be assumed pthread_t is an integer and on windows platform it in fact is not an integer. Attached is my solution to abstract out checks for valid PID's so that it will work with windows and any other pthread implementation that is similar. For each backend that gets ported to mingw and uses threads, it will need to switch to use sanei_thread_is_invalid(pid) instead of (pid == -1). That was not done as a part of this test patch.
