(Dwarf_Die die,
Dwarf_Half attr, Dwarf_Bool
*ret_bool, Dwarf_Error *err);
dwarf_hasattr
() tests whether the debugging
information entry referenced in argument die contains
the attribute named by argument attr. Legal values for
argument attr are those denoted by the
DW_AT_*
constants in the DWARF specification.
If the named attribute is present in the debugging information
entry, function dwarf_hasattr
() returns a non-zero
value in the location pointed to by argument ret_bool.
If the named attribute is not present, a zero is written instead.
If argument err is not NULL, it will be used to return an error descriptor in case of an error.
dwarf_hasattr
() returns
DW_DLV_OK
. In case of an error, it returns
DW_DLV_ERROR
and sets argument
err.
dwarf_hasattr
() can fail with the following
error:
DW_DLE_ARGUMENT
