hi all,
My standalone compress/decompress works perfect. After i imported compress function to my code, it work perfect. However, after import decompress function, it can't decompress the file. As a result, the file is empty. . After i check, it seems gzread() can't read. but the code is just copy and paste. Please tell me what i did wrong. tks a lot.
+ please remove .c in test1a.txt.myziphaha as the input
+ sample.c is the standalone
+ server.c at line 222 is to call decompress.
test1a.txt.myziphaha.c
sample.c

Hmm... weird.
Do you link the same libraries?
And fred(buffer) above should obviously have been free(buffer).

verything is same.i cppy n pastr from sample.c .you can take a lok at sample.c .tks a lot.very weird

your suggestion doesn't work. Somehow gzread() always return 0 . but in sample.c, it can return proper value.

I have tried all ways, but fail. if I just run sample to decompress it, it works. do you see anything wrong?
ASKER
I solved it :) reason is I call decompress before fclose() hihi
