// STL common functionality
|
|
//
|
|
// Some aspects of STL are core language concepts that should be used from all C++ code, regardless
|
|
// of whether exceptions are enabled in the component. Common library code that expects to be used
|
|
// from exception-free components want these concepts, but including STL headers directly introduces
|
|
// friction as it requires components not using STL to declare their STL version. Doing so creates
|
|
// ambiguity around whether STL use is safe in a particular component and implicitly brings in
|
|
// a long list of headers (including <new>) which can create further ambiguity around throwing new
|
|
// support (some routines pulled in may expect it). Secondarily, pulling in these headers also has
|
|
// the potential to create naming conflicts or other implied dependencies.
|
|
//
|
|
// To promote the use of these core language concepts outside of STL-based binaries, this file is
|
|
// selectively pulling those concepts *directly* from corresponding STL headers. The corresponding
|
|
// "std::" namespace STL functions and types should be preferred over these in code that is bound to
|
|
// STL. The implementation and naming of all functions are taken directly from STL, instead using
|
|
// "wistd" (Windows Implementation std) as the namespace.
|
|
//
|
|
// Routines in this namespace should always be considered a reflection of the *current* STL implementation
|
|
// of those routines. Updates from STL should be taken, but no "bugs" should be fixed here.
|
|
//
|
|
// New, exception-based code should not use this namespace, but instead should prefer the std:: implementation.
|
|
// Only code that is not exception-based and libraries that expect to be utilized across both exception
|
|
// and non-exception based code should utilize this functionality.
