Reads one byte from the input buffer, avoiding an overrun.
- Returns
- byte read
Definition at line 45 of file lzo.c.
Referenced by get_len().
Decodes a length value in the coding used by lzo.
- Parameters
-
x | previous byte value |
mask | bits used from x |
- Returns
- decoded length value

Referenced by av_lzo1x_decode().
Copies bytes from input to output buffer with checking.
- Parameters
-
cnt | number of bytes to copy, must be >= 0 |
Definition at line 85 of file lzo.c.
Referenced by av_lzo1x_decode().
Copies previously decoded bytes to current position.
- Parameters
-
back | how many bytes back we start, must be > 0 |
cnt | number of bytes to copy, must be > 0 |
cnt > back is valid, this will copy the bytes we just copied, thus creating a repeating pattern with a period length of back.
