[basic.scope.param] (original) (raw)

A function parameter (including one appearing in alambda-declarator) or function-local predefined variable ([dcl.fct.def]) has function parameter scope.

The potential scope of a parameter or function-local predefined variable begins at its point of declaration.

If the nearest enclosing function declarator is not the declarator of a function definition, the potential scope ends at the end of that function declarator.

Otherwise, if the function has a function-try-block the potential scope ends at the end of the last associated handler.

Otherwise the potential scope ends at the end of the outermost block of the function definition.

A parameter name shall not be redeclared in the outermost block of the function definition nor in the outermost block of any handler associated with a function-try-block.
