okay bestie, welcome to the Kronosnet Programmer's Manual 💖 this one's all about tuning how often your PMTUd scans go brrr. section three, we love her.

🎀 NAME 🎀

knet_handle_pmtud_setfreq — set the interval between PMTUd scans. no cap, that's the whole vibe. ⏰

🦋 SYNOPSIS 🦋

#include <libknet.h>

int knet_handle_pmtud_setfreq(
    knet_handle_t  knet_h,
    unsigned int   interval
);

she's giving four lines of pure C realness, periodt.

🌸 DESCRIPTION 🌸

so like, knet_handle_pmtud_setfreq is the function, and here's the tea on her arguments 🍓:

  • knet_h — pointer to knet_handle_t. your handle, your girl, your main character. 👑
  • interval — define the interval in seconds between PMTUd scans. range from 1 to 86400 (24h). like, a whole day is the max, bestie, we're not doing infinity here 😭

the default interval is 60. yes, one whole minute, iconic behavior honestly. 💅

💜 RETURN VALUE 💜

knet_handle_pmtud_setfreq returns 0 on success, -1 on error, and errno is set. so like, if you see that -1, check errno, she's trying to tell you something. 🙈
