In the gzip library, what's the difference between "uncompress" and "gzopen"?

Question

There are some functions for unpacking in zlib library (zlib version 1.2.3)

I want to unzip the source zip file (.gz) using a function uncompress. It does not work (error code -3), but gzopen. It still doesn't work when I entered the payload pointer (passing the gzip header) to uncompress.

So the question is:

• What are the valid arguments for the uncompress function?
• If he needs a different format, how can I do it?

Answer 1

zlib. . : gzip zlib?
