libgphoto2_port — cross-platform port access library
#include <gphoto2/gphoto2_port.h>
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.
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.
