DISEQUENCE_COMPARE

The DISEQUENCE_COMPARE macro compares two Microsoft® DirectInput® sequence numbers, compensating for wraparound.

DISEQUENCE_COMPARE(dwSequence1, cmp, dwSequence2) \
                ((int)((dwSequence1) - (dwSequence2)) cmp 0)

Parameters

dwSequence1

First sequence number to compare.

cmp

One of the following comparison operators: ==, !=, <, >, <=, or >=.

dwSequence2

Second sequence number to compare.

Return Values

Returns a nonzero value if the result of the comparison specified by the cmp parameter is true, or zero otherwise.

Remarks

The following example checks whether the dwSequence1 parameter value precedes the dwSequence2 parameter value chronologically.

BOOL Sooner = (DISEQUENCE_COMPARE(dwSequence1, <, dwSequence2));
