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 `dontthrow` attribute to most libc functions This will help C++ code that uses exceptions to be tinier. For example, this change shaves away 1000 lines of assembly code from LLVM's libcxx, which is 0.7% of all assembly instructions in the entire library. 2024-01-09 09:26:03 +00:00			`void _extend(void , size_t, void *, int, intptr_t) libcesque;`
