Returns the low 32 bits of the platform's monotonic counter.
|
||||
|
||||
The platform's monotonic counter is comprised of two 32 bit quantities:
|
||||
the high 32 bits and the low 32 bits.
|
||||
During boot service time the low 32 bit value is volatile: it is reset to
|
||||
zero on every system reset and is increased by 1 on every call to this function.
|
||||
This function is only available at boot services time.
|
||||
Before calling ExitBootServices() the operating system would call this function
|
||||
to obtain the current platform monotonic count.
