Example: Effect of Forward Declarations on the Data Model

In the following figure, struct Foo does not use the P128 data model in effect at the time of its forward-declaration. Instead, struct Foo uses the LLP64 data model in effect at the time struct Foo is fully declared.

Figure 325. Example of a Forward Declaration Based on the LLP64 Data Model


 

#pragma datamodel(P128) 
struct Foo; //forward declaration
#pragma datamodel(LLP64)
struct Foo {
char* string; // this pointer is 8-byte because LLP64 datamodel
// was in effect for the struct definition.
};
#pragma datamodel(pop)
#pragma datamodel(pop)
