RCVRESPMSG(3)

💖 RCVRESPMSG(3) 💖

okay bestie, come closer, we're gonna talk about RcvRespMsg from the gpib crew — and yes she's a manual page, and yes she ate 🌸

---

✨ NAME ✨

RcvRespMsg — read data 👑 like that's literally it, that's the whole job

---

🦋 SYNOPSIS 🦋

#include <gpib/ib.h>

void RcvRespMsg(int board_desc, void *buffer, long count,
                int termination);

no return value, no drama, she just does the thing 💅

---

🌈 DESCRIPTION 🌈

okay so. RcvRespMsg() reads data off the bus. FR FR that's the vibe. But — and this is the part where you gotta pay attention, bestie — a device must already have been addressed as talker (and the board as listener) before you call this function. You cannot just roll up uninvited, that's not the energy we're bringing today 🙈

Addressing can be handled with the ReceiveSetup() function. she's the one who does the introductions ✨

Up to count bytes get read into the array you point at with buffer. So count is like… the seat limit. Don't overflow, that's giving chaos 💀

Now the termination argument — she specifies the 8-bit end-of-string character whose reception will terminate a read. And it must be a value from 0 to 255. No mystery numbers, no edge cases, the range is the range, periodt ⭐

termination can also be set to the 'STOPend' constant, in which case no end-of-string character will be used at all. Iconic. Very lowkey minimalist of her 🎀

and heads up — assertion of the EOI line will always end a read. always. it does not care about your plans. it does not care about your termination setting. EOI said what it said 🔥

alsooo, you might find it simpler to use the slightly higher level function Receive(), since it does not require addressing and reading of data to be performed separately. she's the "one-stop shop" version, she handles both steps so you don't gotta do the two-part choreography 💜 main character energy, honestly
