    NAME

    di_walk_lnode - traverse libdevinfo lnodes
     
    

    SYNOPSIS

    cc [ flag... ] file... -ldevinfo [ library... ] 
    #include <libdevinfo.h>
    
    int di_walk_lnode(di_node_t root, uint_t flag, void *arg,
        int (*lnode_callback)(di_lnode_t link, void *arg));
    

     

    PARAMETERS

    root

    The handle to the root node of the subtree to visit.

    flag

    Specify 0. Reserved for future use.

    arg

    A pointer to caller-specific data.

    lnode_callback

    The caller-supplied callback function.

     

    DESCRIPTION

    The di_walk_lnode() function visits all nodes in the subtree rooted at root. For each node found, the caller-supplied function lnode_callback() is invoked for each lnode associated with that node. The return value of lnode_callback() specifies subsequent walking behavior where that node is the specified endpoint of the link.  

    RETURN VALUES

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

    The callback function lnode_callback() can return one of the following:

    DI_WALK_CONTINUE

    Continue walking.

    DI_WALK_TERMINATE

    Terminate the walk immediately.

     

    ERRORS

    The di_walk_lnode() function will fail if:

    EINVAL

    An argument is invalid.
