#include

int
dwarf_formsig8(
Dwarf_Attribute
attr,
Dwarf_Sig8 *ret,
Dwarf_Error *err);
Function
dwarf_formsig8() sets the location pointed
to by argument
ret to the 64-bit type
signature that is the value of the attribute referenced by argument
attr. The form of argument
attr must be
DW_FORM_ref_sig8.
If argument
err is not NULL, it will be used to
return an error descriptor in case of an error.
Function
dwarf_formsig8() returns
DW_DLV_OK on success. In case of an error,
it returns
DW_DLV_ERROR and sets argument
err.
Function
dwarf_formsig8() may fail with the
following errors:
-
-
- [

- 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.
