i want to make a program that accept a file and chechs if it is
readable and writable and give appropriate messeage ?
i can make program to accpet filename from command line and open it in
any omde and write data in it, but to know its permission is seems
tricky, is there apecific function available ?

Not in Standard C.
If you're using a POSIX-compliant system, look for stat(2) and fstat(2).

Yes, but you need to ask in a group for your system. If it's UNIX or
Linux, I suggest or
If it's for Windows then
might be appropriate. Also
take a look at the man pages on your system, (if it's a UNIX), or
browse Microsoft's MSDN online documentation, for Windows.
