The BOOST_PP_NOT_EQUAL macro compares two values for inequality.

Usage

BOOST_PP_NOT_EQUAL(x, y)

Arguments

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.
Previously, this macro could not be used inside BOOST_PP_WHILE.  There is no longer any such restriction because this macro no longer uses BOOST_PP_WHILE.
