// A factory function for creating a shared_ptr which creates
|
||
|
|
// an object and its owning shared_ptr with one allocation, similar
|
||
|
|
// to make_shared<T>(). It also supports postconstructors
|
||
|
|
// and predestructors through unqualified calls of adl_postconstruct() and
|
||
|
|
// adl_predestruct, relying on argument-dependent
|
||
|
|
// lookup to find the appropriate postconstructor or predestructor.
|
||
|
|
// Passing arguments to postconstructors is also supported.
|
||
|
|
//
|

|

// based on make_shared.hpp and make_shared_access patch from Michael Marcin
