NAME
       di_devlink_dup, di_devlink_free - copy and free a devlink object

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

       di_devlink_t di_devlink_dup(di_devlink_t devlink);

       int di_devlink_free(di_devlink_t devlink);

PARAMETERS
       devlink	  An opaque handle to a devlink.

DESCRIPTION
       Typically,  a  di_devlink_t  object  is	only  accessible  from	within	the  scope of the di_devlink_walk(3DEVINFO) callback function. The
       di_devlink_dup() function allows the callback function implementation to make a duplicate copy of the di_devlink_t  object.  The  duplicate
       copy is valid and accessible until di_devlink_free() is called.

       The di_devlink_dup() function returns a copy of a devlink object. The di_devlink_free() function frees this copy.

RETURN VALUES
       Upon  successful completion, di_devlink_dup() returns a copy of the devlink object passed in.  Otherwise, NULL is returned and errno is set
       to indicate the error.

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

ERRORS
       The di_devlink_dup() and di_devlink_free() functions will fail if:

       EINVAL	 The devlink argument is not a valid handle.

       The di_devlink_dup() function can set errno to any error value that can also be set by malloc(3C).
