Typedef Documentation

typedef enum DtShmPoolCreationMode_enum DtShmPoolCreationMode

DtShmPoolCreationMode enumerates different methods available to pool manager to create a shared memory region.

'Normal' - create a new shared memory region if one with the same name does not already exist, otherwise attach to existing pool. 'Exclusive' - create a new shared memory region if one with the same name does not already exist, otherwise throw an exception. 'Graceful Takeover' - same as normal. May imply different side effects within calling routines. 'Ruthless Takeover' - create a new shared memory region if one with the same name does not already exist, otherwise destroy existing pool and create a new one (i.e. The Nuclear Option - only to be employed when subscribers terminate while still attached)
