Structure defining parameters for the HeapMemMP module.
String HeapMemMP_Params::name |
Name of this instance.
The name (if not NULL) must be unique among all HeapMemMP instances in the entire system. When creating a new heap, it is necessary to supply an instance name. The name does not have to be persistent. The supplied string is copied into persistent memory.
UInt16 HeapMemMP_Params::regionId |
Shared region ID
The index corresponding to the shared region from which shared memory will be allocated.
SizeT HeapMemMP_Params::sharedBufSize |
Size of shared buffer
This is the size of the buffer to be used in the HeapMemMP instance. The actual buffer size in the created instance might actually be less than the value supplied in 'sharedBufSize' because of alignment constraints.
It is important to note that the total amount of shared memory required for a HeapMemMP instance will be greater than the size supplied here. Additional space will be consumed by shared instance attributes and alignment-related padding.
GateMP_Handle HeapMemMP_Params::gate |
GateMP used for critical region management of the shared memory
Using the default value of NULL will result in use of the GateMP system gate for context protection.
