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 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.
