DWARF_SETERRARG(3)     FreeBSD Library Functions Manual     DWARF_SETERRARG(3)

NAME
     dwarf_seterrarg, dwarf_seterrhand - configure error handling

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     Dwarf_Ptr
     dwarf_seterrarg(Dwarf_Debug dbg, Dwarf_Ptr arg);

     Dwarf_Handler
     dwarf_seterrhand(Dwarf_Debug dbg, Dwarf_Handler handler);

DESCRIPTION
     These functions may be used by applications to configure error handling
     callbacks.  The error handling scheme used by the library is described in
     dwarf(3).

     Function dwarf_seterrarg() may be used to set the callback argument
     passed to a configured error handler at the time it is invoked.  Argument
     arg is the callback argument being set.  Argument dbg can be a debug
     context allocated by a prior call to dwarf_init(3), or can be NULL to
     indicate that the library-wide callback argument is to be set.

     Function dwarf_seterrhand() may be used to associate an error handler
     denoted by argument handler with the DWARF debug context descriptor
     denoted by argument dbg.  Argument dbg should be a debug context
     allocated by a prior call to dwarf_init(3), or may be NULL to indicate
     that the library-wide error handler is to be set.

RETURN VALUES
     Function dwarf_seterrhand() returns the previous error handler associated
     with argument dbg.  If argument dbg is NULL, function dwarf_seterrhand()
     returns the previous library-wide error handler.

     Function dwarf_seterrarg() returns the previous callback argument
     associated with argument dbg.  If argument dbg is NULL, function
     dwarf_seterrarg() returns the previous library-wide callback argument.

COMPATIBILITY
     The behavior of these functions when argument dbg is NULL is a local
     extension.

ERRORS
     These functions do not set an error code.
