Hi all.

I am writing a c program under gnu/Linux, in which I need to know if a
file of a particular name exists. The only way I can think of checking
for this is to attempt to open a file of a given name in read-only
mode. If it opens, the file exists, if the FILE stream is NULL, the
file doesn't exist. However, doing this for a good number of files
would be inefficient in my opinion. So, I was wondering if there is a
function which will simply tell me if a file of a given name exists or
not, sort of like calling ls, although I don't actually want to be
literally doing that either from within the program? Thanks.

Greg
