28 | \brief Tests any two sequences for inequality. | |
29 | ||
30 | sequence = First sequence. | |
31 | ... = variadic parameters, maximum of 2. | |
32 | ||
33 | The first variadic parameter is required and is the second sequence to test. | |
34 | The optional second variadic parameter is a VMD type as a filter. | |
35 | ||
36 | The macro tests any two sequences for inequality. For sequences to be unequal | |
37 | either the VMD types of each sequence must be unequal or the individual elements of the | |
38 | sequence must be unequal. | |
39 | ||
40 | The single optional parameter is a filter. The filter is a VMD type which specifies | |
41 | that both sequences to test must be of that VMD type, as well as being equal to | |
42 | each other, for the test to fail, else it succeeds. | |
43 | ||
44 | returns = 1 upon success or 0 upon failure. Success means that the sequences are | |
45 | unequal or, if the optional parameter is specified, that the sequences are | |
46 | not of the optional VMD type; otherwise 0 is returned if the sequences | |
47 | are equal. | |
48 | ||
49 | The macro is implemented as the complement of BOOST_VMD_EQUAL, so that whenever | |
50 | BOOST_VMD_EQUAL would return 1 the macro returns 0 and whenever BOOST_VMD_EQUAL | |
51 | would return 0 the macro would return 1. | |
