@ -552,8 +552,17 @@ def _c_field_is_member_of_case_or_bitcase(field):
def _c_helper_fieldaccess_expr(prefix, field=None):
"""
turn prefix, which is a list of tuples (name, separator, Type obj) into a string
representing a valid name in C (based on the context)
if field is not None, append the field name as well
representing a valid field-access-expression in C (based on the context)
if field is not None, append access to the field as well.
"separator" is one of the C-operators "." or "->".
A field access expression can consist of the following components:
* struct/union member access from a value with the "."-operator
* struct/union member access from a pointer with "->"-operator
* function-call of an accessor function:
This is used when a xcb-field is not contained in a struct.
This can, e.g., happen for fields after var-sized fields, etc.
