NAME

       libgphoto2_port - cross-platform port access library

SYNOPSIS

       #include <gphoto2/gphoto2_port.h>

DESCRIPTION

       The libgphoto2_port library was written to provide libgphoto2(3) with a generic way of
       accessing ports. In this function, libgphoto2_port is the successor of the libgpio
       library.

       Currently, libgphoto2_port supports serial (RS-232) and USB connections, the latter
       requiring libusb to be installed.

       The autogenerated API docs will be added here in the future.

ENVIRONMENT VARIABLES

       IOLIBS If set, defines the directory where the libgphoto2_port library looks for its I/O
              drivers (iolibs). You only need to set this on OS/2 systems and broken/test
              installations.

       LD_DEBUG
              Set this to all to receive lots of debug information regarding library loading on
              ld based systems.

       USB_DEBUG
              If set, defines the numeric debug level with which the libusb library will print
              messages. In order to get some debug output, set it to 1.
