LARGE_INTEGER RtlExtendedIntegerMultiply (  IN LARGE_INTEGER  Multiplicand, IN LONG  Multiplier )

Definition at line 117 of file largeic.c. References Multiplier. Referenced by MiAttemptPageFileExtension(). 00124 : 00125 00126 This function multiplies a signed large integer by a signed integer and 00127 returns the signed large integer result. 00128 00129 N.B. An overflow is possible, but no exception is generated. 00130 00131 Arguments: 00132 00133 Multiplicand - Supplies the multiplicand value. 00134 00135 Multiplier - Supplies the multiplier value. 00136 00137 Return Value: 00138 00139 The large integer result is returned 00140 00141 --*/ 00142 { 00143 LARGE_INTEGER Result; 00144 00145 Result.QuadPart = Multiplicand.QuadPart * (LONGLONG)Multiplier; 00146 return (Result); 00147 } }
