NEW ISSUE: Review types supported in C Service interfaces

[Bryan Aupperle <aupperle@us.ibm.com>]

Target: C C&I Specification CD03
 
Description:
The conformance items in section 8.1 and
8.2 are inconsistent with the WSDL mapping rules defined in section 10.3.
 
Proposal:
 
8.1 Local Services
 
The return type and types of parameters of
a function of a local service MUST be one of:

• Any fundamental or compound types as defined by C. [CPP80001]

8.2 Remotable Services
 
For a remotable service being called by another
service the data exchange semantics is by-value.  The return type
and types of the parameters of a function of a remotable interface MUST
be one of:

• Any of the C types specified in Section 10.3.1 and 10.3.2.  These types may be passed by-value or by-pointer.  Unless the function and client indicate that they allow by-reference semantics (See Section 2.1.2), a copy will be explicitly created by the runtime for any parameters passed by-pointer.
• An SDO DATAOBJECT.  This type may be passed by-value or by-pointer.  Unless the function and client indicate that they allow by-reference semantics (See Section 2.1.2), a copy will be explicitly created by the runtime for any parameters passed by-pointer. A deep-copy of the DATAOBJECT will be created by the runtime for any parameters passed by-value or by-pointer. [CPP80002]
