PCAP_SET_BUFFER_SIZE(3PCAP)

💖 pcap_set_buffer_size(3PCAP) — bestie's guide to the buffer 💖

okay so welcome to pcap_set_buffer_size from the 3PCAP manual, bestie, and lemme tell you this one is SHORT but it's iconic. it's giving "small function, big responsibility" energy. ✨

🎀 NAME 🎀

pcap_set_buffer_size — set the buffer size for a capture handle that is not yet activated. that's it. that's the whole vibe. she sets a number and dips. 💅

🌸 SYNOPSIS 🌸

#include <pcap/pcap.h>

int pcap_set_buffer_size(pcap_t *p, int buffer_size);

look at her. two args. no drama. no cap. 🦋

✨ DESCRIPTION ✨

so pcap_set_buffer_size() sets the buffer size that's gonna get used on a capture handle when the handle is activated, and it sets it to buffer_size.

and like — heads up, bestie — buffer_size is in units of bytes. bytes!! not kilobytes, not vibes, not "a lil bit." bytes. 💀

so the flow is literally: you set it now, it kicks in later when the handle gets activated. not before. it's a "manifesting" situation. 🧚

💜 RETURN VALUE 💜

• 0 — slay, it worked, success, ate, no notes. 👑
• PCAP_ERROR_ACTIVATED — yeahhh you called it on a capture handle that's already been activated. too late bestie, the buffer's already locked in. 😭

fr fr: set the buffer size before you activate. this function is strictly a pre-activation girlie. 🫶

• pcap_create(3PCAP)

the whole squad, honestly. go read pcap_create and pcap_activate if you wanna see how she fits into the bigger picture. iykyk. ⭐

this lil masterpiece is from the 3 January 2014 era of the PCAP_SET_BUFFER_SIZE(3PCAP) manual page — oldie but a goodie, and yes she still serves. go set those bytes, bestie, and remember: pre-activation only. periodt. 💖🎀🦋✨
