• SDL_IO_SEEK_SET: seek from the beginning of data
• SDL_IO_SEEK_CUR: seek relative to current read point
• SDL_IO_SEEK_END: seek relative to the end of data
If this stream can not seek, it will return -1.
FUNCTION PARAMETERS
context
a pointer to an SDL_IOStream structure.
offset an offset in bytes, relative to whence location; can be negative.
