The BOOST_PP_NOT_EQUAL_D macro compares two values for inequality.

Usage

BOOST_PP_NOT_EQUAL_D(d, x, y)

Arguments

d
This argument is ignored.
x
The left operand of the comparison.  Valid values range from 0 to BOOST_PP_LIMIT_MAG.
y
The right operand of the comparison.  Valid values range from 0 to BOOST_PP_LIMIT_MAG.

Remarks

If x is equal to y, this macro expands to 0.  Otherwise, it expands to 1.
This macro is deprecated.  It only exists for backward compatibility.  Use BOOST_PP_NOT_EQUAL instead.
