Seeding of typed memory regions
Under QNX Neutrino, typed memory objects are defined from the memory regions specified in the asinfo section of the system page. Thus, typed memory objects map directly to the address space hierarchy (asinfo segments) defined by startup. The typed memory objects also inherit the properties defined in asinfo, namely the physical address (or bounds) of the memory segments.
Naming of typed memory regions
The names of typed memory regions are derived directly from the names of the asinfo segments. The asinfo section itself describes a hierarchy, and so the naming of typed memory object is a hierarchy. The name may contain intermediate / characters that are considered as path component separators.
Pathname space and typed memory
The typed memory name hierarchy is exported through the process manager namespace under /dev/tymem. Applications can list this hierarchy, and look at the asinfo entries in the system page to get information about the typed memory.
