|
|
\brief Conditionally causes an error to be generated.
|
|
|
|
... = variadic parameters, maximum of 2 will be considered.
|
|
Any variadic parameters beyond the maximum of 2 are just ignored.
|
|
|
|
The first variadic parameter is:
|
|
|
|
cond = A condition that determines whether an assertion occurs. Valid values range from 0 to BOOST_PP_LIMIT_MAG.
|
|
|
|
The second variadic parameter (optional) is:
|
|
|
|
errstr = An error string for generating a compiler error when using the VC++ compiler.
|
|
The VC++ compiler is incapable of producing a preprocessor error so when the 'cond'
|
|
is 0, a compiler error is generated by outputting C++ code in the form of:
|
|
|
|
typedef char errstr[-1];
|
|
|
|
The errstr defaults to BOOST_VMD_ASSERT_ERROR if not supplied.
|
|
It is only relevant for VC++.
|
|
|
|
returns = If cond expands to 0, this macro causes an error. Otherwise, it expands to nothing.
|
|
For all compilers other than Visual C++ the error is a preprocessing error.
|
|
For Visual C++ the error is caused by output invalid C++: this error could be
|
|
masked if the invalid output is ignored by a macro which invokes this macro.
