/*
 * termux-compat.h - Compatibility shim for missing libc declarations in Termux
 *
 * Android Bionic lacks some glibc/POSIX functions that native modules expect.
 * This header provides syscall-based wrappers or stubs for them.
 *
 * Usage: CXXFLAGS="-include /path/to/termux-compat.h"
 *        This force-includes the header before every source file.
