\fn void PHYSFS_getCdRomDirsCallback(PHYSFS_StringCallback c, void *d) \brief Enumerate CD-ROM directories, using an application-defined callback.

Internally, PHYSFS_getCdRomDirs() just calls this function and then builds a list before returning to the application, so functionality is identical except for how the information is represented to the application.

Unlike PHYSFS_getCdRomDirs(), this function does not return an array. Rather, it calls a function specified by the application once per detected disc:

\code

static void foundDisc(void *data, const char *cddir) { printf(“cdrom dir [%s] is available.\n”, cddir); }

// … PHYSFS_getCdRomDirsCallback(foundDisc, NULL); \endcode

This call may block while drives spin up. Be forewarned.

\param c Callback function to notify about detected drives. \param d Application-defined data passed to callback. Can be NULL.
