27 | \brief Tests whether a sequence is a Boost PP tuple. | |
28 | ||
29 | The macro checks to see if a sequence is a Boost PP tuple. | |
30 | A Boost PP tuple is preprocessor tokens enclosed by a set of parentheses | |
31 | with no preprocessing tokens before or after the parentheses. | |
32 | ||
33 | sequence = a possible tuple | |
34 | ||
35 | returns = 1 if the sequence is a Boost PP tuple. | |
36 | 0 if it is not. | |
