memory_resource* set_default_resource( memory_resource* r)noexcept; | (library fundamentals TS) | |
Ifr is not null, sets the default memory resource pointer tor; otherwise, sets the default memory resource pointer tonew_delete_resource().
Thedefault memory resource pointer is used by certain facilities when an explicit memory resource is not supplied. The initial default memory resource pointer is the return value ofnew_delete_resource().
This function is thread-safe. Every call toset_default_resourcesynchronizes with (seestd::memory_order) the subsequentset_default_resource andget_default_resource calls.
Returns the previous value of the default memory resource pointer.
gets the defaultmemory_resource(function)[edit] | |
returns a static program-widememory_resource that uses the globaloperator new andoperator delete to allocate and deallocate memory(function)[edit] |
