/** | |
Divides a 64-bit unsigned integer by a 32-bit unsigned integer and | |
generates a 32-bit unsigned remainder. | |
This function divides the 64-bit unsigned value Dividend by the 32-bit | |
unsigned value Divisor and generates a 32-bit remainder. This function | |
returns the 32-bit unsigned remainder. | |
@param Dividend A 64-bit unsigned value. | |
@param Divisor A 32-bit unsigned value. | |
