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 asso‐
ciated.
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.
