The DISEQUENCE_COMPARE macro compares two DirectInput sequence numbers, compensating for wraparound.
#define DISEQUENCE_COMPARE(dwSequence1,cmp,dwSequence2) \((int)((dwSequence1) - (dwSequence2)) cmp 0)
Returns a nonzero value if the result of the comparison specified by the cmp parameter is true, or zero otherwise.
The following example checks whether the dwSequence1 parameter value precedes the dwSequence2 parameter value chronologically.
BOOL Sooner = (DISEQUENCE_COMPARE(dwSequence1, <, dwSequence2));
