KnRegisterPort8(), KnRegisterPort16(), KnRegisterPort32()

These functions are declared in the coresrv/io/ports.h file.

Retcode KnRegisterPort8(rtl_uint16_t port, Handle *outRid);

Retcode KnRegisterPort16(rtl_uint16_t port, Handle *outRid);

Retcode KnRegisterPort32(rtl_uint16_t port, Handle *outRid);

These functions register an eight-, sixteen-, or thirty-two-bit port, respectively, with the port address and assign the outRid handle to it.

Return rcOk if the port allocation is successful.

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