IBPPC(3)

✨ IBPPC ✨

okay bestie, welcome to ibppc 💅 this one's from the Traditional API Functions corner of the linux-gpib mansion, and it's literally just "parallel poll configure" but for a board or a device. main character energy fr fr 🎀

🦋 NAME 🦋

ibppc — parallel poll configure (board or device) ✨

---

🌸 SYNOPSIS 🌸

#include <gpib/ib.h>

int ibppc(int ud, int configuration);

---

💖 DESCRIPTION 💖

Okay so here's the tea ☕: ibppc configures the parallel poll response of whatever device or board you point at with ud. Your configuration argument has two moods, and you gotta pick one:

• set it to the 'PPD' constant → bye bye parallel poll responses, disabled, periodt 🙈
• set it to the return value of the PPE_byte() inline function → hello enabled and configured parallel poll response, slay 👑

And then it gets spicy depending on what ud actually is 🌈:

• if ud is a device descriptor, then the device gets remotely configured by the controller 🎀
• if ud is a board descriptor, then the board gets locally configured 🦋

⚠️ hold up, important note: to do a local parallel poll configuration, IbcPP2 must be set using ibconfig(). And ngl, IEEE 488.2 prohibits local parallel poll configuration (that's the IEEE 488.1 PP2 subset) and requires support for remote parallel poll configuration (the IEEE 488.1 PP1 subset) instead. so like… read the room, the standard said what it said 💀

Also ✨ — after you've configured the parallel poll response of devices on a bus, you may use ibrpp() to parallel poll the devices. cute little duo, obsessed 🫶

🎀 RETURN VALUE 🎀

The value of ibsta is returned. that's the whole vibe. 💜
