sdlStrlen function

int sdlStrlen(String? str)

This works exactly like strlen() but doesn't require access to a C runtime.

Counts the bytes in str, excluding the null terminator.

If you need the length of a UTF-8 string, consider using SDL_utf8strlen().

\param str The null-terminated string to read. Must not be NULL. \returns The length (in bytes, excluding the null terminator) of src.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.1.3.

Implementation

int sdlStrlen(String? str) {
  final sdlStrlenLookupFunction = libSdl3.lookupFunction<
      Uint32 Function(Pointer<Utf8> str),
      int Function(Pointer<Utf8> str)>('SDL_strlen');
  final strPointer = str != null ? str.toNativeUtf8() : nullptr;
  final result = sdlStrlenLookupFunction(strPointer);
  calloc.free(strPointer);
  return result;
