KnRegisterPorts()

This function is declared in the coresrv/io/ports.h file.

Retcode KnRegisterPorts(rtl_uint16_t port, rtl_size_t size, Handle *outRid);

This function registers a range of ports (memory area) with the base address port and the specified size (in bytes) and assigns the outRid handle to it.

Returns rcOk if allocation of the port range is successful.

For a usage example, see KnIoPermitPort().

If a range of ports is no longer being used, it must be freed by using the KnIoClose() function.
