/* Definitions for ScanPostAmble */
/*
* ScanPostAmble reads the postamble of a DVI file from the (stdio)
* file specified in its first argument. It is handed two pointers to
* functions. The first (ScanPostAmble's second argument) is called
* after the header information has been read, and given a pointer to a
* PostAmbleInfo structure. It is the job of this function to extract the
* required information from this structure (which is deallocated when
* ScanPostAmble returns).
*
* The second function is called once for each font definition occurring in
* the postamble, and is given a pointer to a PostAmbleFont structure. This
* function should do whatever the device needs to read the actual font.
*
* If the DVI file appears malformed, ScanPostAmble will print an error
* message and exit. (Drastic, perhaps, but effective.)
