SAM_W...AL_SET(3)

💖 SAM_WARN_SIGNAL_SET(3) 💖

okay bestie, welcome to the Corosync Cluster Engine Programmer's Manual — yes, the whole thing, and yes we're doing this one together 🫶

✨ NAME ✨

sam_warn_signal_set — set the warn signal, that's it, that's the vibe 💅

🌸 SYNOPSIS 🌸

#include <corosync/sam.h>

cs_error_t sam_warn_signal_set (int warn_signal);

like. one function. one int. we love a low-maintenance icon 👑

🦋 DESCRIPTION 🦋

so sam_warn_signal_set is the lil function you call to configure the warning signal — the one that gets sent before your app gets actually, for-real killed for being unresponsive 😭

think of it as the "hey bestie, you good?" text before the block button. iconic behaviour honestly.

the default value is SIGTERM. and plot twist — you can pass SIGKILL here to emulate the "not warning signal send" behaviour 🫣 no warning, just straight to the consequences, main character energy fr fr.

💀 RETURN VALUE 💀

this call returns the CS_OK value if it's successful. otherwise, an error gets returned. no cap, that's the whole deal.

🙈 ERRORS 🙈

• CS_ERR_BAD_HANDLE — the component was not initialized by calling sam_initialize(3), or it was already finalized. like, girl, you have to actually start things before you can use them 💀

⭐ SEE ALSO ⭐

sam_initialize(3)

also dropping the rest of the error crew here because they live in this section for some reason and I refuse to leave them out 🎀:

• CS_ERR_TRY_AGAIN — resource temporarily unavailable 😤
• CS_ERR_INVALID_PARAM — invalid argument, bestie, check ur inputs 🍓
• CS_ERR_ACCESS — permission denied, not for you i guess 🚫
• CS_ERR_LIBRARY — the connection failed 💔
• CS_ERR_INTERRUPT — system call interrupted by a signal ✋
• CS_ERR_NOT_SUPPORTED — the requested protocol/functionality is not supported 🙅
• CS_ERR_MESSAGE_ERROR — incorrect auth message received 🤨
• CS_ERR_NO_MEMORY — not enough memory to complete the requested task, she's full 😭

lowkey reminder: SIGTERM is the default, SIGKILL means the warning never sends. don't be shocked when there's no warning. you asked for that. 💅
