di_minor_t di_minor_next(di_node_t node, di_minor_t minor);

minor
Handle to the current minor node or DI_MINOR_NIL.

node

Device node with which the minor node is associated.

The di_minor_next() function returns a handle to the next minor node for the device node node. If minor is DI_MINOR_NIL, a handle to the first minor node is returned.

Upon successful completion, a handle to the next minor node is returned. Otherwise, DI_MINOR_NIL is returned and errno is set to indicate the error.

The di_minor_next() function will fail if:

EINVAL

Invalid argument.

ENOTSUP

Minor node information is not available in snapshot.

ENXIO

End of minor node list.
