Detailed Description

Image structure definition.

The IMAGE structure is defined here Supports shared memory, low latency IPC through semaphores

Dynamic allocation within IMAGE: IMAGE includes a pointer to an array of IMAGE_METADATA (usually only one element, >1 element for polymorphism) IMAGE includes a pointer to an array of KEYWORDS IMAGE includes a pointer to a data array

Bug:: No known bugs.
