5.8.5 Delay Import Address Table (IAT)

The delay IAT is referenced by the delay import descriptor via the pIAT field. This is the working copy of the entry point function pointers that resides in the data section of the image and initially refer to the delay load thunks. The delay load helper is responsible for updating these pointers with the real entry points so that the thunks are no longer in the calling loop. The function pointers are access via the expression pINT->u1.Function.
