.SH NAME
libgphoto2_port \- cross-platform port access library
.SH "SYNOPSIS"
.nf
#include <gphoto2_port\&.h>

.PP
The libgphoto2_port library was written to provide \fBlibgphoto2\fR(3) with a generic way of accessing ports\&. In this function, libgphoto2_port is the successor of the libgpio library\&.
.PP
Currently, libgphoto2_port supports serial (RS\-232) and USB connections, the latter requiring libusb to be installed\&.
.PP
The autogenerated API docs will be added here in the future\&.
.SH "ENVIRONMENT VARIABLES"

IOLIBS
If set, defines the directory where libgphoto2_port looks for its I/O drivers (camlibs)\&.
.TP
