Abstract:
|
|
|
|
Generic C language interface to PUMA disassembler.
|
|
|
|
This is designed to expose the functionality of the PUMA disassembler
|
|
via a simple C language API. It is not intended to be as flexible or
|
|
as efficient as using the DIS class interface. It is intended to provide
|
|
"least common denominator" access to the disassembler for C code which
|
|
does not have stringent performance demands. A minimum set of types is
|
|
exposed, and they are named so as to minimize the chance of collisions.
