/*
 * spawn.h - POSIX spawn stub header for Termux
 *
 * Android Bionic supports posix_spawn() since API 28 (Android 9.0),
 * but Termux's NDK headers may not include spawn.h.
 * This stub provides the necessary declarations so native modules
 * (e.g. koffi) can compile and link against the system libc.
 *
 * Based on Android Open Source Project (Apache-2.0 / BSD)
