Detailed Description

The port operations.

These operations are to be implemented and set by the port library, which drives the lowlevel protocol (serial, usb, etc.).

They are acessed using the accessor functions, like gp_port_open(), gp_port_read() and gp_port_write().

The documentation for this struct was generated from the following file:
