Returns the filename of the next file from the
directory. The filenames are returned in the order in which
they are stored by the filesystem.
Please note the fashion in which
readdir()'s return value is checked in the examples
below. We are explicitly testing whether the return value is
identical to (equal to and of the same type as--see Comparison Operators
for more information) FALSE
since otherwise, any directory entry whose name evaluates to
FALSE will stop the loop
(e.g. a directory named "0").
Note that readdir() will return
the . and
.. entries. If you don't want these, simply strip them
out:
