sdlReadStorageFile function storage

bool sdlReadStorageFile(Pointer<SdlStorage> storage, String? path, Pointer<Void> destination, int length,)

Synchronously read a file from a storage container into a client-provided buffer.

The value of length must match the length of the file exactly; call SDL_GetStorageFileSize() to get this value. This behavior may be relaxed in a future release.

\param storage a storage container to read from. \param path the relative path of the file to read. \param destination a client-provided buffer to read the file into. \param length the length of the destination buffer. \returns true if the file was read or false on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.2.0.
