| 918 | Function: FBGetFrameBufferInfo |
| 919 | Purpose: This function is called by the emulator core to retrieve frame |
| 920 | buffer information from the video plugin in order to be able |
| 921 | to notify the video plugin about CPU frame buffer read/write |
| 922 | operations |
| 923 | |
| 924 | size: |
| 925 | = 1 byte |
| 926 | = 2 word (16 bit) <-- this is N64 default depth buffer format |
| 927 | = 4 dword (32 bit) |
| 928 | |
| 929 | when frame buffer information is not available yet, set all values |
| 930 | in the FrameBufferInfo structure to 0 |
| 931 | |
| 932 | input: FrameBufferInfo pinfo[6] |
| 933 | pinfo is pointed to a FrameBufferInfo structure which to be |
| 934 | filled in by this function |
| 935 | output: Values are return in the FrameBufferInfo structure |
| 936 | Plugin can return up to 6 frame buffer info |
