💖 LIBGPHOTO2_PORT(3) 💖

okay bestie, welcome to the gPhoto2 Reference (the man page edition ✨). this is the manual for libgphoto2_port, and it's literally the cross-platform port access library. yes, the one. buckle up 🎀

🌸 NAME 🌸

libgphoto2_port — the cross-platform port access library. she talks to ports so you don't have to. 💅

✨ SYNOPSIS ✨

#include <gphoto2/gphoto2_port.h>

that's it. that's the whole vibe. include the header and you're in. 🫶

🦋 DESCRIPTION 🦋

so here's the lore: libgphoto2_port was written to give libgphoto2(3) a generic way of accessing ports. in this function, libgphoto2_port is the successor of the libgpio library — glow up complete, no cap 👑

currently, libgphoto2_port supports serial (RS-232) and USB connections. the USB one? yeah, she requires libusb to be installed. non-negotiable, sorry bestie 😭

the autogenerated API docs will be added here in the future. so like… watch this space 👀

🌈 ENVIRONMENT VARIABLES 🌈

these are the lil settings that change how she behaves. read them, love them 💜

  • IOLIBS — if set, this defines the directory where the libgphoto2_port library looks for its I/O drivers (iolibs). 🧚 you only need to set this on Windows systems and on broken/test installations. everyone else can chill.
  • LD_DEBUG — set this to all to receive lots of debug information regarding library loading on ld based systems. prepare to be absolutely flooded, it's giving firehose 💀
  • USB_DEBUG — if set, this defines the numeric debug level with which the libusb library will print messages. in order to get some debug output, set it to 1. start small, babe 🔥
