These functions create attribute descriptors belonging to the
|
|
|
|
|
.Sq constant

|
argument
|
|
|
|
|
.Ar die .
|
|
|
|
|
.Pp
|
|
|
|
|
Argument
|
|
|
|
|
.Ar dbg
|
|
|
|
|
should reference a DWARF producer instance allocated using

|
|
|
|
.Xr dwarf_producer_init 3
|
|
|
|
|
or
|
|
|
|
|
.Xr dwarf_producer_init_b 3 .

.Dv DW_FORM_data1 ,
|
|
|

|
|
|
|
.Dv DW_FORM_data8 ,
|
|
|
|
|
depending on the size of the value specified in argument
|
|
|
|
|
.Ar value .
|
|
|
|

.Pp
|
|
|
|
|
If argument
|
|
|
|
|
.Ar err
|
|

|
|
|
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
|
|
|
|
