libssh2_knownhost_readline(3)

💖 libssh2_knownhost_readline — read a known host line 💖

okay bestie, so this one lives in the libssh2 manual, and it's literally about reading one single line of a known hosts file. that's it. that's the whole vibe. ✨

✨ SYNOPSIS ✨

#include <libssh2.h>

int
libssh2_knownhost_readline(LIBSSH2_KNOWNHOSTS *hosts,
                           const char *line, size_t len, int type):

🌸 DESCRIPTION 🌸

You're telling libssh2 to take a buffer and read it as if it were a line straight out of a known hosts file. no cap, that's the whole job.

• line — points to the start of the line 👈
• len — the length of the line, in bytes 📏
• type — says what kind of file this is, and LIBSSH2_KNOWNHOST_FILE_OPENSSH is the only format supported rn. this file is normally found chilling at ~/.ssh/known_hosts 🏠

💅 RETURN VALUE 💅

It returns a regular libssh2 error code, bestie:

• negative values = error codes 😭
• 0 = success 🎉 (slay)

🦋 AVAILABILITY 🦋

Added in libssh2 1.2 — so she's been iconic for a minute. 👑
