KDK_NET_GET_PROC_PORT(3)

📦 version 3.0.1.4, in arch rolling, ubuntu resolute, ubuntu stonking

💖 KDK_NET_GET_PROC_PORT 💖

okay bestie, welcome to kdk_net_get_proc_port(3) from the Library Functions Manual — yes she's a section 3 girlie and she's here to hand you the port of a process, no cap. 🎀

✨ NAME ✨

kdk_net_get_proc_port — 获取进程对应端口

🦋 SYNOPSIS 🦋

#include <libkynetinfo.h>

extern char **kdk_net_get_proc_port();

Link with -lkynetinfo.

🌸 Detailed Description 🌸

The main character function of this interface is, literally, to obtain the port corresponding to the process. That's the whole vibe. 💅

🫶 RETURN VALUE 🫶

  • On success, it returns the port corresponding to the process, of type char **, ending with a NULL character. Bestie it's generated by alloc so you have to recycle it with kdk_net_freeall — do not ghost your allocations, that's giving memory leak. 😭
  • On error, it returns NULL.

🔥 EXAMPLES 🔥

She's long, she's thorough, she ate:
