+ *     (if preconditions holds) but in different order.
+ *     The first, standard mode is the so called 'unbuffered' mode.
+ *     In this mode, this function simply scan the target directory, build
+ *     the full path for each entry and return to the caller in filesystem
+ *     order. The other operating mode is the 'buffered' mode, and
+ *     it's triggered using a non-zero value for parameter 'sort' in
+ *     tc_dirlist_open (see above). When in buffered mode, this function
+ *     will return the full path of each entry in target directory in
+ *     lexicogrpaphical order. Otherwise full path is given using
+ *     filesystem order.
+ *
+ * Parameters:
+ *     tcdir: TCDirList structure (descriptor) to use.
+ * Return Value:
+ *     a constant pointer to full path of next entry NULL there are no
+ *     more entries, or if an internal error occurs.
+ * Side effects:
+ *     in unbuffered mode, target directory will be scanned one time.
+ * Preconditions:
+ *     referred directory *MUST NOT CHANGE* until descriptor
+ *     will be closed via tc_dirlist_close().
+ *     'tcdir' was initialized calling tc_dirlist_open().
