chown function
Change the owner and group of FILE.
If the owner or group is specified as -1, then that ID is not changed.
If the call fails a PosixException is thrown with the value of errno.
Implementation
void chown(
String filename,
int owner,
int group,
) {
final cFilename = filename.toNativeUtf8();
clearErrno();
_chown ??= Libc().dylib.lookupFunction<
ffi.Int32 Function(ffi.Pointer<Utf8>, ffi.Uint32, ffi.Uint32),
_dart_chown>('chown');
final results = _chown!(
cFilename,
owner,
group,
);
malloc.free(cFilename);
if (results != 0) {
final error = errno();
throw PosixException('chown failed error: ${strerror(error)}', error);
}
}
