libgphoto2_port (3) Linux Manual Page
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.
