These routines are statically linked in the caller's executable and
|
||
|
|
are callable from user mode.

// macro, This for loop is used lots of places, so I've

// centralized it here. The idea is that is builds the Levelxxx names

// based on the Dest and Src parameters (destination level, source level)
|

|
// using token pasting. So the macro looks like bad, but once you see
|

|
|
// what it's doing, the invocation in the code is easier reading.

|
||
|
|
//
|
||
|
|
// BUILD_LENGTH_ARRAY(BytesRequired, 10, 101, Wksta)
|
||
|

// expands to
|
||
|

//
|

|
// for (i = 0; NetpWksta10_101[i].Source != MOVESTRING_END_MARKER; i++) {
|
||
|

// if (*((PCHAR) pLevel101 + NetpWksta10_101[i].Source)) {
|

// Level10_101_Length[i] =
