Hello

I want to do something like this:


while (<still files>)
{
// process files found

}

This is in the FAQ.

A: See if you can use the opendir() and readdir() functions, which
are part of the POSIX standard and are available on most Unix
variants. Implementations also exist for MS-DOS, VMS, and other
systems. (MS-DOS also has FINDFIRST and FINDNEXT routines which
do essentially the same thing.) readdir() only returns file
names; if you need more information about the file, try calling
stat(). To match filenames to some wildcard pattern, see
question 13.7.
