LIBGPHOTO2_PORT(3)      The gPhoto2 Reference (the man      LIBGPHOTO2_PORT(3)


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.
