DWARF_SETERRARG(3)      NetBSD Library Functions Manual     DWARF_SETERRARG(3)


NAME

     dwarf_seterrarg, dwarf_seterrhand -- configure error handling


LIBRARY

     library ``libdwarf''


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 con-
     text allocated by a prior call to dwarf_init(3), or can be NULL to indi-
     cate 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 allo-
     cated 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 associ-
     ated 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.
