di_link_spectype, di_link_to_lnode - return libdevinfo link information SYNOPSIS
cc [ flag... ] file... -ldevinfo [ library... ] #include <libdevinfo.h> int di_link_spectype(di_link_t link); di_lnode_t di_link_to_lnode(di_link_t link, uint_t endpoint); PARAMETERS
link A handle to a link. endpoint specifies the endpoint of the link, which should correspond to either DI_LINK_TGT or DI_LINK_SRC DESCRIPTION
The di_link_spectype() function returns libdevinfo link information. The di_link_to_lnode() function takes a link specified by link and returns the lnode corresponding to the link endpoint specified by end- point. RETURN VALUES
The di_link_spectype() function returns the spectype parameter flag that was used to open the target device of a link, either S_IFCHR or S_IFBLK. Upon successful completion, di_link_to_lnode() returns a handle to an lnode. Otherwise, DI_LINK_NIL is returned and errno is set to indi- cate the error. ERRORS
The di_link_to_lnode() function will fail if: EINVAL An argument is invalid. ATTRIBUTES

di_walk_link(3DEVINFO) Device Information Library Functions di_walk_link(3DEVINFO) NAME
di_walk_link - traverse libdevinfo links SYNOPSIS
cc [ flag... ] file... -ldevinfo [ library... ] #include <libdevinfo.h> int di_walk_link(di_node_t root, uint_t flag, uint_t endpoint, void *arg, int (*link_callback)(di_link_t link, void *arg)); PARAMETERS
root The handle to the root node of the subtree to visit. flag Specify 0. Reserved for future use. endpoint Specify if the current node being visited should be the target or source of an link, either DI_LINK_TGT or DI_LINK_SRC arg A pointer to caller-specific data. link_callback The caller-supplied callback function. DESCRIPTION
The di_walk_link() function visits all nodes in the subtree rooted at root. For each node found, the caller-supplied function link_call- back() is invoked for each link associated with that node where that node is the specified endpoint of the link. The return value of link_callback() specifies subsequent walking behavior. See RETURN VALUES. RETURN VALUES
Upon successful completion, di_walk_link() returns 0. Otherwise, -1 is returned and errno is set to indicate the error. The callback function, link_callback(), can return one of the following: DI_WALK_CONTINUE Continue walking. DI_WALK_TERMINATE Terminate the walk immediately. ERRORS
The di_walk_link() function will fail if: EINVAL An argument is invalid. ATTRIBUTES
