I want to modify STL to suite my requirement, So I download sgi STL ,
Now I am reading one file of them "concept_checks.h", I don't how it
can check the concept and report error when compile,
such as follow semantics,I need some anotate.
#define __STL_REQUIRES(__type_var, __concept) \
do { \
void (*__x)( __type_var ) = __concept##_concept_specification<
__type_var >\
::__concept##_requirement_violation; __x = __x; } while (0)
#define __STL_GENERATOR_CHECK(__func, __ret) \
do { \
__ret (*__x)( __func&) = \
_STL_GENERATOR_ERROR< \
__func, __ret>::__generator_requirement_violation; \
__x = __x; } while (0)
#define __STL_CLASS_REQUIRES(__type_var, __concept) \
typedef void (* __func##__type_var##__concept)( __type_var ); \
template <__func##__type_var##__concept _Tp1> \
struct __dummy_struct_##__type_var##__concept { }; \
static __dummy_struct_##__type_var##__concept< \
__concept##_concept_specification< \
__type_var>::__concept##_requirement_violation> \
__dummy_ptr_##__type_var##__concept
I need some help to anotate these sentence, complete file is follow ,it

Modifying STL files cannot be considered a good practice. There should
be other ways to solve your problem.
If you will be so kind to describe your problem before the point you
have decided to modify STL, there might be one who will see how to
solve it without modifing STL at all.
Or, at least, what is the exact reqiurement STL does not fit for you?
Thanks.
Alex
