explicit monotonic_buffer_resource(memory_resource* upstream); monotonic_buffer_resource(size_t initial_size, memory_resource* upstream);

Preconditions: upstream is the address of a valid memory resource.

initial_size, if specified, is greater than zero.

Effects: Sets upstream_rsrc to upstream andcurrent_buffer to nullptr.

If initial_size is specified, sets next_buffer_size to at least initial_size; otherwise sets next_buffer_size to animplementation-defined size.

monotonic_buffer_resource(void* buffer, size_t buffer_size, memory_resource* upstream);

Preconditions: upstream is the address of a valid memory resource.

buffer_size is no larger than the number of bytes in buffer.

Effects: Sets upstream_rsrc to upstream,current_buffer to buffer, andnext_buffer_size to buffer_size (but not less than 1), then increases next_buffer_sizeby an implementation-defined growth factor (which need not be integral).

~monotonic_buffer_resource();

Effects: Calls release().
