"The existence test, F_OK".

PHP Code:



status=access("/etc/fstab1",F_OK); 
 
if(status==-1) 
{ 
    //doesn't exist OR uid doesn't have permission 
} 
else 
{ 
    //ok 
}

Hope I got this right. Cheers.

Dude - the man page *tells* you what headers you should include!

PS:
I think you should probably acknowledge that Jim McNamara was only trying to help. "access()" and "stat()" are two excellent replies. There are many others, depending on your platform and development environment.

PPS:
If it still doesn't work, please:
a) Cut/paste example code that you wrote (it probably shouldn't be much longer than 4 or 5 lines, tops!)
b) Cut/paste your "build" command line (this will tell us several important facts, including your compiler version)
c) Cut/paste the results of running your program
