NAME
       di_walk_minor - traverse libdevinfo minor nodes

SYNOPSIS
       cc [ flag... ] file... -ldevinfo [ library... ]
       #include <libdevinfo.h>

       int  di_walk_minor(di_node_t  root,  const  char  *minor_nodetype, uint_t flag, void *arg, int (*minor_callback)(di_node_t node, di_minor_t
       minor, void *arg));

PARAMETERS
       arg	       Pointer to caller- specific user data.

       flag	       Specify 0. Reserved for future use.

       minor	       The minor node visited.

       minor_nodetype  A character string specifying the minor data type, which may be one of the types defined by the Solaris DDI framework,  for
		       example, DDI_NT_BLOCK. NULL matches all minor_node  types. See ddi_create_minor_node(9F).

       node	       The device node with which to  the minor node is associated.

       root	       Root of subtree to visit.

DESCRIPTION
       The di_walk_minor() function visits all minor nodes attached to device nodes in a subtree rooted at root. For each  minor node that matches
       minor_nodetype, the caller-supplied function minor_callback() is invoked.  The walk terminates immediately  when  minor_callback()  returns
       DI_WALK_TERMINATE.

RETURN VALUES
       Upon successful completion, di_walk_minor() returns 0. Otherwise, -1 is returned and errno is set to indicate the error.

       The minor_callback() function returns one of the following:

       DI_WALK_CONTINUE        Continue to visit subsequent minor data nodes.

       DI_WALK_TERMINATE       Terminate the walk immediately.

ERRORS
       The di_walk_minor() function will fail if:

       EINVAL		       Invalid argument.
