rfio_readdir
reads the directory opened by
rfio_opendir.
This routine returns a pointer to a structure containing the current directory
entry.
dirp
specifies the pointer value returned by
rfio_opendir.
NOTES
Only the fields d_name, d_reclen and on some platforms d_namlen are filled.
For LCG directories, a multi-threaded application will need to initialize itself the Cthread (LCG Thread Interface) library ; this is done by including "shift/Cthread_api.h" and calling the function Cthread_init() at the beginning. Otherwise accessing LCG directories will not be thread-safe. See Cthread(3).
RETURN VALUE
This routine returns a pointer to a structure containing the current directory
entry if the operation was successful or NULL if the end of the directory was
reached or if the operation failed. In the latter case,
serrno
is set appropriately.
