Constructs a synchronized_pool_resource
.
1-4) Constructs a
The overloads not taking opts as a parameter uses a default constructed instance of pool_options as the options. The overloads not taking upstream as a parameter uses the return value of std::pmr::get_default_resource
synchronized_pool_resource
using the specified upstream memory resource and tuned according to the specified options. The resulting object holds a copy of upstream but does not own the resource to which upstream points.The overloads not taking opts as a parameter uses a default constructed instance of pool_options as the options. The overloads not taking upstream as a parameter uses the return value of std::pmr::get_default_resource
5) Copy constructor is deleted.
Parameters
opts | - | a std::pmr::pool_options struct containing the constructor options |
upstream | - | the upstream memory resource to use |
Exceptions
1-4) Throws only if a call to the
allocate()
function of the upstream resource throws. It is unspecified if or under what conditions such a call takes place.
