Public Attributes
int	indexSz
	Number of four byte hash table entries to create.
int	maxKeys
	Maximum number of keys-value pairs expected in table.
int	maxKLen
	The maximum acceptable key length.
int	mode
	Filemode for the newly created file.
signed char	multW

Detailed Description

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.
