This header file contains type definitions for the NT TDI, NDI,
|

DDI, and PDI interfaces which are not specific to a single interface.

// from the beginning of the immediate parent structure.

|
|
// string through an I/O interface which does not allow embedded pointers.

// buffer bytes in the allocation.
