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 Windows 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.
