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.
