- memory model
- =============
- The documentation indicates that LZO requires 32 bit integers. It's
- not the integer size that really matters, though, but the memory
- model. If your memory model allows to access pointers at 32 bit
- offsets, then there is no problem at all - LZO works fine on my
- old Atari ST, which has 16 bit integers and a flat 32 bit memory model.
- 16 bit MSDOS using 'huge' 32 bit pointers is a workaround for this.
-
- While with some minor changes LZO also would work with a strict
- 16 bit memory model, I don't officially support this because
- this limits the maximum block size to 64k - and this makes the
- library incompatible with other platforms, i.e. you cannot decompress
- larger blocks compressed on those platforms.

-
- public integral types
- =====================
- - lzo_uint: used as size_t, must be 32 bits or more for compatibility
- - lzo_uint32: *must* be 32 bits or more
- - lzo_ptr_t: must be big enough to hold all bits of a lzo_voidp
- - lzo_bool: can store the values 0 and 1
-
- - lzo_byte: unsigned char (memory model)
- - lzo_voidp: void pointer (memory model)
-
-
- public function types
- =====================
- - lzo_compress_t:
- - lzo_decompress_t:
- - lzo_progress_callback_t:
-
-
- naming conventions
- ==================
-
- e.g. LZO1X-999:
- !---------- algorithm category
- !--------- algorithm type
- !!!----- compression level (1-9, 99, 999)
-
- LZO1*: strictly byte aligned
- LZO2*: uses bit-shifting, slower decompression
