/* The model is:
|
|
*
|
|
* BinParser has an offset associated with it. This offset can be
|
|
* manipulated with methods
|
|
*
|
|
* goto - go to absolute position from file start
|
|
* goto_rel - go to relative position
|
|
* goto_record_rel - skip the given number of records
|
|
* align - move forward until aligned to given width
|
|
* save/restore - save/restore the current offset (stack)
|
|
*
|
|
* and queried with
|
|
*
|
|
* get_offset - return current offset in bytes from start
|
|
*
|
|
* data can be retrieved with
|
|
*
|
|
* get_uint - return a uint of given width, and skip
|
|
* get_string - return a null terminated stringm, and skip
|
|
* get_pstring - return a 'pascal' string with given length
|
|
*
|
|
* get_uint_field - return the named field
|
|
*
|
|
* formats should probably be definable as static data.
|
|
*
|
|
* A bin parser also has an associated "status" with it. This can be
|
|
* OK, or error. It is ok to use a parser with an error status, but
|
|
* the data returned will not be meaningfull.
