p Argument .Ar die should reference a debugging information entry allocated using .Xr dwarf_new_die 3 .

p Function .Fn dwarf_add_AT_const_value_signedint creates a .Dv DW_AT_const_value attribute descriptor containing the signed value specified by argument .Ar value . The created attribute descriptor will have DWARF form .Dv DW_FORM_sdata .

p Function .Fn dwarf_add_AT_const_value_unsignedint creates a .Dv DW_AT_const_value attribute descriptor containing the unsigned value specified by argument .Ar value . The created attribute descriptor will have DWARF form .Dv DW_FORM_udata .

p Function .Fn dwarf_add_AT_const_value_string creates a .Dv DW_AT_const_value attribute descriptor containing the string pointed to by the NUL-terminated argument .Ar str . The created attribute descriptor will have DWARF form .Dv DW_FORM_strp .

p If argument .Ar err is not NULL, it will be used by these functions to store error information in case of an error. .Sh RETURN VALUES On success, these functions return the created attribute descriptor. In case of an error, these functions return .Dv DW_DLV_BADADDR and set the argument .Ar err . .Sh ERRORS These functions can fail with: l -tag -width ".Bq Er DW_DLE_ARGUMENT" t Bq Er DW_DLE_ARGUMENT Either of the arguments .Ar die or .Ar str was NULL. t Bq Er DW_DLE_MEMORY An out of memory condition was encountered during execution. .El .Sh SEE ALSO .Xr dwarf 3 , .Xr dwarf_add_AT_name 3 , .Xr dwarf_add_AT_signed_const 3 , .Xr dwarf_add_AT_string 3 , .Xr dwarf_add_AT_unsigned_const 3 , .Xr dwarf_new_die 3
