A basic managed windows shared memory creation class. Initializes the shared memory segment. Inherits all basic functionality from basic_managed_memory_impl<CharType, AllocationAlgorithm, IndexType> Unlike basic_managed_shared_memory, it has no kernel persistence and the shared memory is destroyed when all processes destroy all their windows_shared_memory objects and mapped regions for the same shared memory or the processes end/crash.
Warning: basic_managed_windows_shared_memory and basic_managed_shared_memory can't communicate between them.
basic_managed_windows_shared_memory
public
construct/copy/destruct() ;
Default constructor. Does nothing. Useful in combination with move semantics
(create_only_t, name, size, addr = , permissions & perm = permissions());
Creates shared memory and creates and places the segment manager. This can throw.
(open_or_create_t, name, size, addr = , permissions & perm = permissions());
Creates shared memory and creates and places the segment manager if segment was not created. If segment was created it connects to the segment. This can throw.
(open_only_t, name, addr = );
Connects to a created shared memory and its segment manager. This can throw.
(open_copy_on_write_t, name, addr = );
Connects to a created shared memory and its segment manager in copy_on_write mode. This can throw.
(open_read_only_t, name, addr = );
Connects to a created shared memory and its segment manager in read-only mode. This can throw.
(open_or_create_t, name, size, addr = , permissions & perm = permissions());
Creates shared memory and creates and places the segment manager if segment was not created. If segment was created it connects to the segment. This can throw.
(open_only_t, name, addr = );
Connects to a created shared memory and its segment manager. This can throw.
(open_copy_on_write_t, name, addr = );
Connects to a created shared memory and its segment manager in copy_on_write mode. This can throw.
(open_read_only_t, name, addr = );
Connects to a created shared memory and its segment manager in read-only mode. This can throw.
(basic_managed_windows_shared_memory && moved) ;
Moves the ownership of "moved"'s managed memory to *this. Does not throw
basic_managed_windows_shared_memory & (basic_managed_windows_shared_memory && moved) ;
Moves the ownership of "moved"'s managed memory to *this. Does not throw
~();
Destroys *this and indicates that the calling process is finished using the resource. All mapped regions are still valid after destruction. When all mapped regions and basic_managed_windows_shared_memory
objects referring the shared memory are destroyed, the operating system will destroy the shared memory.
basic_managed_windows_shared_memory
public member functions(basic_managed_windows_shared_memory & other) ;
Swaps the ownership of the managed mapped memories managed by *this and other. Never throws.
