Function
Return the validity of a specified element of an invalid-component handle when the queries come in sequential order.
Syntax
#include <dx/dx.h>
int DXIsElementValidSequential(InvalidComponentHandle handle, int index)
int DXIsElementInvalidSequential(InvalidComponentHandle handle, int index)
Functional Details
Access with either routine is generally faster than with DXIsElementInvalid or DXIsElementValid.
The result reflects both the initial conditions of handle when it was created with DXCreateInvalidComponentHandle, and of the effects of any calls to DXSetElementInvalid, DXSetElementValid, DXInvertValidity, DXSetAllValid, or DXSetAllInvalid.
| Note: | Accesses must be in sequential order; if they are not, the results may be incorrect. |
Return Value
DXIsElementInvalidSequential returns TRUE (1) if element index is marked invalid, and returns FALSE (0) otherwise.
DXIsElementValidSequential returns TRUE (1) if element index is marked valid, and returns FALSE (0) otherwise.
