Function
dwarf_attroffset() retrieves the
section-relative offset of the attribute descriptor referenced by argument
at.
Argument
ret_off should point to a location
that is to hold the returned section-relative offset. If argument
err is non-NULL, it is used to return an
error descriptor in case of an error.
On success, function
dwarf_attroffset() returns
DW_DLV_OK.
In case of an error, it returns
DW_DLV_ERROR
and sets argument
err.
This function is an extension to the
DWARF(3) API.
The
dwarf_attroffset() function may fail with the
following errors:
-
-
- [
DW_DLE_ARGUMENT]
- Either of the arguments at
or ret_off was NULL.
