💅 libssh2_channel_window_write_ex — bestie's guide to the write window 💅

ok so real talk, you're out here in the libssh2 man pages (manual name is literally just libssh2, slay) and you found this one. It's libssh2_channel_window_write_ex, and it's here to tell you how much you can write before the universe (aka the channel) makes you wait. Let's get into it 🫶

✨ NAME ✨

libssh2_channel_window_write_ex — check the status of the write window 👀

No cap, that's the whole job. It checks the status of the write window. That's it. That's the girl.

---

🌸 SYNOPSIS 🌸

#include <libssh2.h>

unsigned long
libssh2_channel_window_write_ex(LIBSSH2_CHANNEL *channel,
                                unsigned long *window_size_initial)

look at her. two args. very demure, very mindful. 🎀

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function checks the status of the write window, and what it hands back is the number of bytes which may be safely written on the channel without blocking. literally that's the vibe check you needed before you go dumping data into the void.

and bestie, listen — window_size_initial is that optional friend you can bring along. If you pass it (if you pass it!! no pressure!!), it will be populated with the size of the initial window as defined by the channel_open request. So it's not the current window, it's the OG window size from way back at the channel_open request. important distinction, don't get it twisted 💖

if you don't pass window_size_initial, that's fine. she just won't fill anything in. no drama.

---

⭐ RETURN VALUE ⭐

Returns the number of bytes which may be safely written on the channel without blocking.

that's your number, that's your green light, go off 👑 — as long as you stay under it, you're not gonna block.

💀 ERRORS 💀

...yeah bestie there's literally nothing here. The original page has this section and then just moves on. Not a single error listed. It's giving mystery, it's giving silence, it's giving ¯\_(ツ)_/¯ 🙈

So like, no documented errors. That's the whole section. We move. 💅
