cuiziwei 0d35e2e0bb system/popen: add dpopen/dpclose fd-based interface ... Add dpopen()/dpclose() as the descriptor-based counterpart of popen()/pclose(), analogous to how dprintf() relates to fprintf(). dpopen() returns a raw file descriptor instead of a FILE stream, avoiding the stdio.h dependency for callers that only need an fd. Refactor popen() as a thin wrapper: dpopen() + fdopen() + FILE container. All pipe creation and process spawning logic now lives in dpopen.c. Also remove the hard dependency on NSH_LIBRARY from SYSTEM_POPEN. When NSH is available, commands are executed through sh -c with full shell syntax support. When NSH is not available, commands are split by whitespace and executed directly via posix_spawnp(). Add CONFIG_SYSTEM_POPEN_MAXARGUMENTS (default 7) to control the argv array size for the no-shell path. Signed-off-by: cuiziwei <cuiziwei@xiaomi.com>		2026-06-02 23:35:28 +08:00
