If
r
is not null, sets the default memory resource pointer to
r
; otherwise, sets the default memory resource pointer to
new_delete_resource()
.
The
default 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 of
new_delete_resource()
.
This function is thread-safe. Every call to
set_default_resource
synchronizes with
(see
std::memory_order
) the subsequent
set_default_resource
and
get_default_resource
calls.
Return value
Returns the previous value of the default memory resource pointer.
