DWARF_FORMUDATA(3)	 BSD Library Functions Manual	    DWARF_FORMUDATA(3)

NAME
     dwarf_formudata, dwarf_formsdata -- return	the value of a CONSTANT	class
     attribute

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_formudata(Dwarf_Attribute attr, Dwarf_Unsigned *ret,
	 Dwarf_Error *err);

     int
     dwarf_formsdata(Dwarf_Attribute attr, Dwarf_Signed	*ret,
	 Dwarf_Error *err);

DESCRIPTION
     These functions return the	value associated with a	DWARF attribute	de-
     scribing a	constant.

     Function dwarf_formudata()	sets the location pointed to by	argument ret
     to	the value of the attribute referenced by argument attr,	treating the
     value as an unsigned quantity.  Argument attr must	have one of the	fol-
     lowing forms: DW_FORM_data1, DW_FORM_data2, DW_FORM_data4,	DW_FORM_data8
     and DW_FORM_udata.

     Function dwarf_formsdata()	sets the location pointed to by	argument ret
     to	the value of the attribute referenced by argument attr,	appropriately
     sign extended.  Argument attr must	have one of the	following forms:
     DW_FORM_data1, DW_FORM_data2, DW_FORM_data4, DW_FORM_data8	and
     DW_FORM_sdata.

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

RETURN VALUES
     These functions return DW_DLV_OK on success.  In case of an error,	they
     return DW_DLV_ERROR and set argument err.

ERRORS
     These functions may fail with the following errors:

     [DW_DLE_ARGUMENT]	     Either of arguments attr or ret was NULL.

     [DW_DLE_ATTR_FORM_BAD]  The attribute referenced by argument attr was not
			     of	a permitted kind.
