Throws a PosixException if an error occurs The result is null-terminated if LEN is large enough for the full name and the terminator.
Implementation
String gethostname() {
const bufSize = 64 + 1;
final cName = malloc.allocate<Utf8>(bufSize);
_gethostname ??= Libc().dylib.lookupFunction<
ffi.Int32 Function(ffi.Pointer<Utf8>, ffi.Uint64),
_dart_gethostname>('gethostname');
final result = _gethostname!(
cName,
bufSize,
);
_throwIfErrno('gethostname', result, cName);
final hostname = cName.toDartString();
malloc.free(cName);
return hostname;
