The BOOST_PP_NOT macro performs a logical NOT on its operand.

Usage

BOOST_PP_NOT(x)

Arguments

x
The value to be converted.  Valid values range from 0 to BOOST_PP_LIMIT_MAG.

Remarks

If x is zero, this macro expands to 1.  Otherwise, it expands to 0.
This macro performs a boolean conversion on its operand before performing the logical NOT operation.  If that conversion is not necessary, use BOOST_PP_COMPL instead.
