DC_BUFFER_GET_SIZE(3)

💖 DC_BUFFER_GET_SIZE(3) 💖

Okay bestie, welcome to a Library Functions Manual page — yes, the manual name is literally “Library Functions Manual,” and this one is short, sweet, and very “small function, big main-character energy.” ✨

🌸 NAME 🌸

dc_buffer_get_size — get the size used by a buffer

🫶 LIBRARY 🫶

library “libdivecomputer” 💅

✨ SYNOPSIS ✨

#include <libdivecomputer/buffer.h>

size_t
dc_buffer_get_size(dc_buffer_t *buffer);

🦋 DESCRIPTION 🦋

Get the number of bytes currently used by buffer, which was previously allocated with dc_buffer_new(3). Like, actually used, not the whole flex. 💖

This is not the same as the capacity, bestie — capacity may be larger. No cap.

Quick vibe check: the returned value is not valid after subsequent calls to change the buffer. So don’t stash it like it’s forever, because it isn’t. 😭

⭐ RETURN VALUES ⭐

Returns the number of bytes used, which may be zero — or zero if buffer is NULL. That’s it, that’s the whole return situation. 🎀

💀 SEE ALSO 💀

This section is empty in the page, for real. The cross-reference dc_buffer_new(3) shows up at the end of AUTHORS below, so I’m keeping it exactly there and not doing any creative rearrangement. 💅

That’s the whole page, bestie 🫶 — cute sign-off time: this footer energy is Debian, January 5, 2017, and DC_BUFFER_GET_SIZE(3) one more time because the footer said so. 💖✨
