libssh2_poll_channel_read(3)

💖 libssh2_poll_channel_read — the libssh2 manual, bestie edition 💖

okay so. this page lives in the libssh2 manual, and we're talking about libssh2_poll_channel_read(3). yes, the third section. yes, we're being fancy about it. 🎀

✨ NAME ✨

libssh2_poll_channel_read — check if data is available

like. literally that's the whole job. vibe check on your read buffer. 🦋

🌸 SYNOPSIS 🌸

#include <libssh2.h>

int
libssh2_poll_channel_read(LIBSSH2_CHANNEL *channel, int extended);

💅 DESCRIPTION 💅

okay bestie, before you get attached: this function is deprecated. Do note use. like, that's the actual wording, and honestly? iconic typo, we're keeping it, but the energy is real — don't use this one. 🙈

so what does it even do. libssh2_poll_channel_read(3) checks to see if data is available in the channel's read buffer. that's it. that's the whole main character moment. and here's the catch: no attempt is made with this method to see if packets are available to be processed. so it's a peek at the buffer and nothing more, no packet-processing intel whatsoever. 😭

if you want the full polling support — the real, complete, everything-bagel version — go use libssh2_poll(3) instead. periodt. 👑

⭐ RETURN VALUE ⭐

• returns 1 when data is available
• returns 0 otherwise

fr fr, those are the only two outcomes. simple queen behaviour. 💖

🫶 SEE ALSO 🫶

• libssh2_poll(3)

🌈 quick recap for the group chat: deprecated, don't use it, it only checks the read buffer, it does NOT check for packets to process, and libssh2_poll(3) is the one you actually want. iykyk. ✨

and that's the page, babe — straight out of libssh2 0.15, dated 14 Dec 2006. ancient. archival. still slaying in the man pages. 🧚💜 mwah, go poll responsibly. 💅
