TR_COMPARE_NETWORK_ADDRESSES (Windows CE 5.0)
This macro uses an arbitrary ordering to set a caller-supplied variable to a value indicating whether a given Token Ring address is greater than, less than, or equal to another given Token Ring address.
VOID TR_COMPARE_NETWORK_ADDRESSES(PCHAR_A,PCHAR_B,PINT_Result);
Parameters
- _A
Points to the first network address. - _B
Points to the second network address. - _Result
Points to a caller-supplied variable in which this macro returns the result of its comparison. The following table shows how _Result relates to the ordering of _A to _B.Value Description < 0 _A is less than _B. > 0 _A is greater than _B. = 0 _A equals _B.
Return Values
None.
Remarks
Token Ring network addresses do not have a defined ordering relationship. Consequently, the results of this macro for unequal addresses depend on the argument ordering.
The TR_COMPARE_NETWORK_ADDRESSES macro is defined as follows.
#define TR_COMPARE_NETWORK_ADDRESSES(_A, _B, _Result) \
{ \
if (*(ULONG UNALIGNED *)&(_A)[2] > \
*(ULONG UNALIGNED *)&(_B)[2]) \
{ \
*(_Result) = 1; \
} \
else if (*(ULONG UNALIGNED *)&(_A)[2] < \
*(ULONG UNALIGNED *)&(_B)[2]) \
{ \
*(_Result) = (UINT)-1; \
} \
else if (*(USHORT UNALIGNED *)(_A) > \
*(USHORT UNALIGNED *)(_B)) \
{ \
*(_Result) = 1; \
} \
else if (*(USHORT UNALIGNED *)(_A) < \
*(USHORT UNALIGNED *)(_B)) \
{ \
*(_Result) = (UINT)-1; \
} \
else \
{ \
*(_Result) = 0; \
} \
}
