Thanks Dan,

i have tried that, but it's not working, i always get a Z_DATA_ERROR.

do you have a code sample?

Sample to do what, compress or decompress? I just open the file with gzopen and then gzwrite or gzread (and of course stick a .gz on the end if I'm creating).

i was trying to store compressed (i.e. gzipped) files as resources, get a pointer to them at run time and decompress using zlib, but i get different errors.

I'm using the inflateInit2, inflate and inflateEnd functions as described in the examples. Also, i am giving inflateInit2 a -15 as second parameter to skip the .gz headers and go straight to the deflated data.

The problem is, none of this works. Has anyone done something like this before?

thanks

i know it works that way, it's just that the fact that it seems to be impossible to do proper in-memory decompression of a gzipped file with zlib, even if it says it can do so, triggered the sportsman in me.

Anyway, i don't have time to play around with that, so i'll go with writing my own compress prog. as you suggested.

Thanks!

Yea that really drove me crazy too! I read many other posts about people trying to decompress gzipped files in memory with zlib on Google Groups and no one seemed to have a solution which is why I originally posted. It seems that zlib can't do this...
