|
|
used by Blizzard in their games.
|
|
|
|
Q: What can i do with libmpq?
|
|

|
|
and manipulate mpq archives.
|
|
|
|
Q: Is it legal?
|
|
A: Yes, i think so. I have no idea why it should not, all informations
|
|
about the fileformat are available.
|
|
|
|
Q: Is there a description of the functions?
|

|
|
|
|
Q: Can i help?
|
|
A: Yes, help is needed, not only with developing, also with testing.
|
|
A good point to start is using a recent SVN version of libmpq and
|
|
trying to use it with every mpq archive you could get :)
|
|
|
|
Q: Can you give a small example to demonstrate the usage?
|
|
A: Of course :) The example below takes first parameter as mpq archive
|
|
and extracts the first file to a buffer.
