Collaboration diagram for CSharedMemory:
Detailed Description
A wrapper around the File Mapping, memory management, API which makes shared memory easier to use. Note that this class creates shared memory and if you pass in a name that's in the Global namespace then the caller needs to have the SeCreateGlobalPrivilege on their account for the code to work without an access denied exception from the constructor.Public Types | |
