Order to ensure proper cleanup of resources, unlink() should beĬalled once (and only once) across all processes which have needįor the shared memory block. Requests that the underlying shared memory block be destroyed. Note that callingĬlose() does not cause the shared memory block itself to be In order toĮnsure proper cleanup of resources, all instances should callĬlose() once the instance is no longer needed. close ( ) ¶Ĭloses access to the shared memory from this instance. To an existing shared memory block, the size parameter is ignored. Memory block may be larger or equal to the size requested. Because some platforms choose to allocate chunks of memoryīased upon that platform’s memory page size, the exact size of the shared Size specifies the requested number of bytes when creating a new shared Or an existing shared memory block is attached ( False). When creating a new shared memory block, if None (theĭefault) is supplied for the name, a novel name will be generated.Ĭreate controls whether a new shared memory block is created ( True) Name is the unique name for the requested shared memory, specified asĪ string. Unlink() method should be called to ensure proper cleanup. When a shared memory block is no longer needed by any process, the Needed by other processes, the close() method should be called. No longer needs access to a shared memory block that might still be May outlive the original process that created them. Particular name and a different process can attach to that same sharedĪs a resource for sharing data across processes, shared memory blocks In this way, one process can create a shared memory block with a Each shared memory block is assigned a unique name. SharedMemory ( name = None, create = False, size = 0 ) ¶Ĭreates a new shared memory block or attaches to an existing shared Or other communications requiring the serialization/deserialization andĬopying of data. Significant performance benefits compared to sharing data via disk or socket Sharing data directly via memory can provide Of data between processes, avoiding the need to instead send messages between Their own process memory space but shared memory permits the sharing Processes are conventionally limited to only have access to Processes to potentially read and write to a common (or shared) region of This style of shared memory permits distinct (though is not necessarily implemented explicitly as such) and does not refer In this module, shared memory refers to “System V style” shared memory blocks SharedMemoryManager, is also provided in the The life-cycle management of shared memory especially across distinct On a multicore or symmetric multiprocessor (SMP) machine. CleanGenius (previously known as MacCleaning developed by EaseUS ) is utility software for Apple Inc.'s macOS.This module provides a class, SharedMemory, for the allocationĪnd management of shared memory to be accessed by one or more processes It is used to clean the potentially unneeded files on the macOS startup disk, uninstall the application by removing its core files, preference files, cache files and proper support files. Downloaded or other files in the macOS Downloads folder.Deleted files in the macOS Trash folder.System and user log files in the macOS Logs folder.System and user Cache files in the macOS Caches folder.This software includes the direct version on EaseUS official website and the App Store version in Apple Inc.'s Mac App Store Features System cleaning ĬleanGenius supports the cleaning of potentially unwanted files or temporary files left by macOS and certain programs, such as Safari. The duplicate function is used to find and remove all duplicated files on the disk. The Uninstall applications function is a replacement for the ordinary Mac remove program method, which is to drag and trash the applications directly. CleanGenius differentiates itself by additionally deleting the files located in directories other than that of the original application, such as preference files, etc. Disk usage ĬleanGenius intuitively marks file/folder size with different colors by Disk Usage function.ĬleanGenius allows the users to manually release the inactive memory in the Mac and reclaim more memory. macOS does not release inactive memory until free memory runs out. When free memory is not enough for the fresh application, macOS will release part of the inactive memory for the new demand. Wired: The used memory for the system and application core components.This mechanism would hit the performance of the application which launches for the first time with the insufficient free memory. Inactive: The used memory for cache purpose.Active: The used memory for the running system and application processes. It stores the information of quit applications. If those applications rerun later, they will be launched notably faster.ĬleanGenius provides an alternate method to eject mounted devices.
