Type Alias ul_next_sys::ULFileSystemOpenFileCallback

pub type ULFileSystemOpenFileCallback = Option<unsafe extern "C" fn(path: ULString) -> ULBuffer>;

Open file for reading and map it to a Buffer.

To minimize copies, you should map the requested file into memory and use ulCreateBuffer() to wrap the data pointer (unmapping should be performed in the destruction callback).

If the file was unable to be opened, you should return NULL for this value.
