This file provides a general interface for SDL to read and write data streams. It can easily be extended to files, memory, etc.
#define RW_SEEK_CUR 1 |
Seek relative to current read point
#define RW_SEEK_END 2 |
Seek relative to the end of data
#define RW_SEEK_SET 0 |
Seek from the beginning of data
