The BOOST_PP_OR macro expands to the logical OR of its operands.

Usage

BOOST_PP_OR(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, this macro expands to 1.  Otherwise, it expands to 0.
This macro performs a boolean conversion on each operand before performing the logical OR operation.  If that conversion is not necessary, use BOOST_PP_BITOR instead.
