The BOOST_PP_XOR macro expands to the logical XOR of its operands.

Usage

BOOST_PP_XOR(p, q)

Arguments

p
The left operand of the operation.  Valid values range from 0 to BOOST_PP_LIMIT_MAG.
q
The right operand of the operation.  Valid values range from 0 to BOOST_PP_LIMIT_MAG.

Remarks

If either p or q is non-zero exclusively, this macro expands to 1.  Otherwise, it expands to 0.
This macro performs a boolean conversion on each operand before performing the logical XOR operation.  If that conversion is not necessary, use BOOST_PP_BITXOR instead.
