Description
FDCompareByteStr compares the values of AStr1
and AStr2
parameters.
Use FDCompareByteStr to compare two TFDByteString objects with case sensitivity. The return value is 0
if AStr1
equals AStr2
, -1
if AStr1
is less than AStr2
, or 1
if AStr1
is greater than AStr2
. The comparison operation is based on the 8-bit ordinal value of each character.
ALen1
and ALen2
represent the length of AStr1
and AStr2
.
