The BOOST_PP_TUPLE_REM macro expands to a macro that removes the parentheses from a tuple.

Usage

BOOST_PP_TUPLE_REM(size)

or

BOOST_PP_TUPLE_REM(size) (v)

Arguments

size
The size of the tuple from which the parentheses are to be removed.  Valid tuple sizes range from 1 to BOOST_PP_LIMIT_TUPLE. 

Remarks

The size argument must be the actual size of the tuple in the non-variadic version.

For the variadic version (v) the size may be left out completely so that the macro can be invoked as BOOST_PP_TUPLE_REM(); you may get a warning from some compilers, but the functionality will still work. If you specify a size in the variadic version, it will be ignored, but the warning from some compilers will not occur.

Note: For Visual C++ 8.0 ( Visual Studio 2005 ) you must specify the correct size argument as in the non-variadic version.
