/* These functions read and write data of the specified endianness, |

dynamically translating to the host machine endianness. |
|
30 |
||
31 |
e.g.: If you want to read a 16 bit value on big-endian machine from |
|
32 |
an open file containing little endian values, you would use: |
|
33 |
value = SDL_ReadLE16(rp); |
|
34 |
Note that the read/write functions use SDL_RWops pointers |
|
35 |
instead of FILE pointers. This allows you to read and write |
|
36 |
endian values from large chunks of memory as well as files |
|
37 |
and other data sources. |
