(library fundamentals TS) | |
The struct std::experimental::pmr::pool_options contains a set of constructor options for std::experimental::pmr::synchronized_pool_resource and std::experimental::pmr::unsynchronized_pool_resource.
Data members
| std::size_t max_blocks_per_chunk |
the maximum number of blocks that will be allocated at once from the upstream memory resource to replenish a pool (public member object) |
| std::size_t largest_required_pool_block |
the largest allocation size that is required to be fulfilled through the pooling mechanism (public member object) |
If the value of max_blocks_per_chunk is zero or greater than an implementation-defined limit, that limit is used instead. The implementation may use a smaller value than is specified and may use different values for different pools.
If the value of largest_required_pool_block is zero or greater than an implementation-defined limit, that limit is used instead. The implementation may use a threshold greater than specified in this field.
