🔗
explicit monotonic_buffer_resource(memory_resource* upstream); monotonic_buffer_resource(size_t initial_size, memory_resource* upstream);
1
#
Preconditions: upstream is the address of a valid memory resource.
initial_­size, if specified, is greater than zero.
2
#
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);
3
#
Preconditions: upstream is the address of a valid memory resource.
buffer_­size is no larger than the number of bytes in buffer.
4
#
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().
