Routine Description:
|
||
|
|
|
||
|
|
This routine computes the total size (fixed and string) of a given
|
||
|
|
structure.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
InStructure - a pointer to the input structure.
|
||
|
|
|
||
|
|
InStructureDesc - the descriptor string for the input structure.
|
||
|
|
|
||
|
|
OutStructureDesc - the descriptor string for the output structure.
|
||
|
|
(May be the same as input, in many cases.)
|
||
|
|
|
||
|
|
MeaninglessInputPointers - if TRUE, then all pointers in the input
|
||
|
|
structure are meaningless. This routine should assume that
|
||
|
|
the first variable data immediately follows the input structure,
|
||
|
|
and the rest of the variable data follows in order.
|
||
|
|
|
||
|
|
Transmission Mode - Indicates whether this structure is part of a response,
|
||
|
|
a request, or both.
|
||
|
|
|
||
|
|
Conversion Mode - Indicates whether this is a RAP-to-native, native-to-RAP,
|
||
|
|
or native-to-native conversion.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
DWORD - number of bytes required for the structure
|
||
|
|
