explicit monotonic_buffer_resource(memory_resource* upstream);
monotonic_buffer_resource(size_t initial_size, memory_resource* upstream);
Requires:
upstream shall be the address of a valid memory resource.
initial_size, if specified, shall be greater than zero.
Effects:
Sets upstream_rsrc to upstream and
current_buffer to nullptr.
If initial_size is specified,
sets next_buffer_size to at least initial_size;
otherwise sets next_buffer_size to an
implementation-defined size.
monotonic_buffer_resource(void* buffer, size_t buffer_size, memory_resource* upstream);
Requires:
upstream shall be the address of a valid memory resource.
buffer_size shall be no larger than the number of bytes in buffer.
Effects:
Sets upstream_rsrc to upstream,
current_buffer to buffer, and
next_buffer_size to buffer_size (but not less than 1),
then increases next_buffer_size
by an implementation-defined growth factor (which need not be integral).
~monotonic_buffer_resource();
Effects:
Calls release().
