okay so real talk: this page is about passing your own lil data around inside libtiff without losing it, and honestly? it's giving genius. let's go 🫶

🌸 NAME 🌸

TIFFClientInfo — it hands you a whole method to pass user defined data from one routine to another. no cap. 💅

---

🎀 SYNOPSIS 🎀

#include <tiffio.h>

void *TIFFGetClientInfo(TIFF *tif, const char *name)

void TIFFSetClientInfo(TIFF *tif, void *data, const char *name)

---

🦋 DESCRIPTION 🦋

so the clientinfo linked list is literally the vibe-transfer system: it gives you a method to hand over user defined data from one routine to another, using the internal tif storage of the libtiff library. it's a lil messenger bag attached to your TIFF struct. iconic.

• TIFFGetClientInfo() — returns a pointer to the data of the named entry in the clientinfo-list. and if the name is not found? NULL gets returned. sorry bestie, nothing there. 😭
• TIFFSetClientInfo() — adds or replaces an entry in the clientinfo-list, using the name and the pointer to the data provided by the caller. new entry, or glow-up of an old one, either way it slays. ✨

💀 DIAGNOSTICS 💀

None.

...yeah. that's it. no drama, no error messages, we're just chilling. 🧚
