MISRA.DECL.EXCPT.SPEC

Function is declared with different exception specifications.

MISRA-C++ Rule 15-4-1 (required): If a function is declared with an exception-specification, then all declarations of the same function (in other translation units) shall be declared with the same set of type-ids.

[NDR 15.4(2)]

Rationale

It is undefined behaviour if a function has different exception-specifications in different translation units.

Example

// Translation unit A
void foo( ) throw ( const char_t * )
{
   throw "Hello World!";
}

// Translation unit B
// foo declared in this translation unit with a different exception
// specification
extern void foo ( ) throw ( int32_t );  // Non-compliant -
                                        // different specifier
void b ( ) throw ( int32_t )
{
   foo ( ); // The behaviour here is undefined.
}
