Here are the questions:
1. Given a file pointer, how do i get the corresponding file descriptor in Linux(kno how to do it in dos)
2.How do i lock a file using only file pointer ?
3.When going through the header files and sources, i came across many functions and variables beginning with underscore(_) and double underscore(__) What do these represent and what is their significance ?
4. Any good links on advanced pointer use.
Thanks in advance
