Detailed Description Encapsulation of shared memory APIs. Using file mapping under Windows, System V shared memory (shm) under Linux. Note: under Linux, an option could be added to prevent a segment to be swapped out. Author: Olivier Cado , Nevrax France Date: 2002 Definition at line 68 of file shared_memory.h. Member Function Documentation void * NLMISC::CSharedMemory::accessSharedMemory (  TSharedMemId    sharedMemId )  [static]   Get access to an existing shared memory segment. The id must be used. Returns: Access address of the segment. Its size was determined at the creation. Definition at line 90 of file shared_memory.cpp. References NLMISC::TSharedMemId. bool NLMISC::CSharedMemory::closeSharedMemory (  void *    accessAddress )  [static]   Close a shared memory segment, given the address returned by createSharedMemory() or accessSharedMemory(). Must be called by each process that called createSharedMemory() or accessSharedMemory(). Definition at line 125 of file shared_memory.cpp. void * NLMISC::CSharedMemory::createSharedMemory (  TSharedMemId    sharedMemId, uint32    size )  [static]   Create a shared memory segment and get access to it. The id must not be used. The id 0x3a732235 is used by the NeL memory manager. Returns: Access address of the segment of the choosen size Definition at line 55 of file shared_memory.cpp. References NLMISC::SharedMemIdsToShmids, and NLMISC::TSharedMemId. void NLMISC::CSharedMemory::destroySharedMemory (  TSharedMemId    sharedMemId, bool    force = false )  [static]   Destroy a shared memory segment (must be call by the process that created the segment, not by the accessors). "Rescue feature": set "force" to true if a segment was created and left out of control (meaning a new createSharedMemory() with the same sharedMemId fails), but before, make sure the segment really belongs to you! Note: this method does nothing under Windows, destroying is automatic. Definition at line 159 of file shared_memory.cpp. References NLMISC::SharedMemIdsToShmids, and NLMISC::TSharedMemId.
