Don't relocate file descriptor memory This change fixes #496 where ASAN spotted a race condition that could happen in multithreaded programs, with more than OPEN_MAX descriptors when using ZipOS or Windows NT, which require tracking open file info and this change fixes that table so it never relocates, thus allowing us to continue to enjoy the benefits of avoiding locks while reading. 2022-09-09 23:54:28 +00:00			`#ifndef COSMOPOLITAN_LIBC_CALLS_EXTEND_INTERNAL_H_`

Add shared memory apis to redbean You can now do things like implement mutexes using futexes in your redbean lua code. This provides the fastest possible inter-process communication for your production systems when SQLite alone as ipc or things like pipes aren't sufficient. 2022-10-06 11:55:26 +00:00			`void _extend(void , size_t, void *, int, intptr_t);`
