Device Information Library Functions     di_devlink_dup(3DEVINFO)



NAME
     di_devlink_dup, di_devlink_free - copy and  free  a  devlink
     object

SYNOPSIS
     cc [ flag... ] file... -ldevinfo [ library... ]
     #include 

     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  acces-
     sible 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).
