DC_BUFFER_PREPEND(3)

✨ NAME ✨

okay so bestie, welcome to dc_buffer_prepend(3) from the Library Functions Manual 💖. The name is literally:

dc_buffer_prepend — prepend to a binary buffer

That’s the whole vibe: we’re prepending to a binary buffer, no cap. 🎀

🎀 LIBRARY 🎀

This one lives in the library “libdivecomputer”. 🫶

🌸 SYNOPSIS 🌸

#include <libdivecomputer/buffer.h>

int
dc_buffer_prepend(dc_buffer_t *buffer, const unsigned char data[],
    size_t size);

💅 DESCRIPTION 💅

Here’s the tea: dc_buffer_prepend prepends size bytes of data to the beginning of buffer 🔥. And buffer has to be one that was previously allocated with dc_buffer_new(3) — like, that’s the whole prerequisite, iykyk. ✨

🦋 RETURN VALUES 🦋

The return value is giving:

• non-zero on success 👑
• zero on memory exhaustion 😭
• zero if buffer is NULL 🙈

periodt. 💅
