Structure and Union Attributes

  • Článek

Use the switch_* attributes to specify the characteristic of a union in a remote procedure call. Use the ignore attribute to designate certain structure or union members as local to the client application.

Attribute Usage
switch Selects the discriminant for an encapsulated union.
switch_is Identifies the discriminant for a nonencapsulated union.
switch_type Identifies the type of the discriminant for a nonencapsulated union.
ignore Designates that a pointer contained in a structure or union and the object indicated by the pointer is not to be transmitted.

 

You can also use the array and sized pointer attributes to specify characteristics of structure or union members.
