Create a new shared memory segment and associated file specified at object instantiation (see New() method). Created segments must be made visible to other processes using the Export() method. This allows the table to be preloaded with initial values before the table is made visible.
- Parameters
-
parms | Create parameters described by CRParms. All uninitialized members in this struct must be specified. |
- Returns
- true - The shared memory was attached, the table can be used.
-
false - The shared memory could not be attached, errno holds reason.
