DWARF_HASATTR(3)	 BSD Library Functions Manual	      DWARF_HASATTR(3)

NAME
     dwarf_hasattr -- check for	the presence of	an attribute

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_hasattr(Dwarf_Die die, Dwarf_Half attr, Dwarf_Bool *ret_bool,
	 Dwarf_Error *err);

DESCRIPTION
     Function dwarf_hasattr() tests whether the	debugging information entry
     referenced	in argument die	contains the attribute named by	argument attr.
     Legal values for argument attr are	those denoted by the DW_AT_* constants
     in	the DWARF specification.

     If	the named attribute is present in the debugging	information entry,
     function dwarf_hasattr() returns a	non-zero value in the location pointed
     to	by argument ret_bool.  If the named attribute is not present, a	zero
     is	written	instead.

     If	argument err is	not NULL, it will be used to return an error descrip-
     tor in case of an error.

RETURN VALUES
     On	success, function dwarf_hasattr() returns DW_DLV_OK.  In case of an
     error, it returns DW_DLV_ERROR and	sets argument err.

ERRORS
     Function dwarf_hasattr() can fail with the	following error:

     [DW_DLE_ARGUMENT]	Either of argument die or ret_bool was NULL.
