I am reporting your reply to the moderators. It seems you dont know what is C++ from the way you answered and you are just replying with bogus replies.

Please reply usefully and only if you know.

thks a lot,

Search for this header file in google: jpeglib.h
You can get it easily from the Independent Jpeg Group.
Check for the documentation on what decompression functions are available in the above said file.:)

hi lucky_star,

I have opened jpeg files before in C. I just dont remember them. And i dont recollect using any special headers for opening the files. Its just the parameters that i am not able to recollect while using the fopen function.

thks,
legolas.
