NAME¶
std::pmr::unsynchronized_pool_resource::unsynchronized_pool_resource - std::pmr::unsynchronized_pool_resource::unsynchronized_pool_resource
Synopsis¶
unsynchronized_pool_resource(); (1) (since C++17)
explicit unsynchronized_pool_resource( std::pmr::memory_resource* (2)
(since C++17)
upstream );
explicit unsynchronized_pool_resource( const (3) (since C++17)
std::pmr::pool_options& opts );
unsynchronized_pool_resource( const std::pmr::pool_options& opts,
std::pmr::memory_resource* upstream (4) (since C++17)
);
unsynchronized_pool_resource( const unsynchronized_pool_resource&
(5) (since C++17)
) = delete;
Constructs an unsynchronized_pool_resource.
1-4) Constructs an unsynchronized_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
use
the return value of std::pmr::get_default_resource() as the upstream memory
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.
