DWARF_ADD_AT_SIGNED_CONST(3)                          Library Functions Manual

NAME
     dwarf_add_AT_signed_const, dwarf_add_AT_unsigned_const -- create and
     attach constant class attributes

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     Dwarf_P_Attribute
     dwarf_add_AT_signed_const(Dwarf_P_Debug dbg, Dwarf_P_Die die,
         Dwarf_Half attr, Dwarf_Signed value, Dwarf_Error *err);

     Dwarf_P_Attribute
     dwarf_add_AT_unsigned_const(Dwarf_P_Debug dbg, Dwarf_P_Die die,
         Dwarf_Half attr, Dwarf_Unsigned value, Dwarf_Error *err);

DESCRIPTION
     These functions create attribute descriptors belonging to the `constant'
     class and attach them to the debugging information entry referenced by
     argument die.

     Argument dbg should reference a DWARF producer instance allocated using
     dwarf_producer_init(3) or dwarf_producer_init_b(3).

     Argument die should reference a debugging information entry allocated
     using dwarf_new_die(3).

     Argument attr specifies the attribute code of the created attribute
     descriptor.

     Function dwarf_add_AT_signed_const() creates an attribute descriptor with
     the signed value specified in argument value.

     Function dwarf_add_AT_unsigned_const() creates an attribute descriptor
     with the unsigned value specified in argument value.

     The attribute created by these function will have one of the DWARF forms
     DW_FORM_data1, DW_FORM_data2, DW_FORM_data4 or DW_FORM_data8, depending
     on the size of the value specified in argument value.

     If argument err is not NULL, it will be used by these functions to store
     error information in case of an error.

RETURN VALUES
     On success, these functions return the created attribute descriptor.  In
     case of an error, these functions return DW_DLV_BADADDR and set the
     argument err.

ERRORS
     These functions can fail with:

     [DW_DLE_ARGUMENT]       Either of the arguments dbg or die was NULL.

     [DW_DLE_MEMORY]         An out of memory condition was encountered during
                             execution.
