buffer = (char*) malloc (length);
Can you explain to me the meaning of "malloc" in this command ?
Thanks

malloc is short for memory allocate. It returns a void pointer. A void pointer can be typed to different types of structures.

See the "man malloc" manpage.

malloc just returns an area of contiguous memory to do with as you please,
sort of like asking for enough rope

Homework ?

If you use Linux, learn how to use the manpages (man malloc would have given you the answer).
If you have an internet connection, you can search for man malloc and get the answer as well.
