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. SEE ALSO
