NSCD_FLUSH_CACHE(3)

💅 NSCD_FLUSH_CACHE(3)

okay bestie, welcome to NSCD_FLUSH_CACHE(3) from the Linux Programmer's Manual — yes, the whole glow-up is happening right here. 🦋

---

🦋 NAME 🦋

nscd_flush_cache — flush the cache of the Name Service Cache Daemon (nscd). Literally what it says on the tin, and honestly? iconic. ✨

✨ SYNOPSIS ✨

#include <libnscd.h>

int nscd_flush_cache(const char *service);

💖 DESCRIPTION 💖

nscd_flush_cache() flushes the specified cache of nscd(8) for the service you pass in. This is important if user or group entries get modified, so that nscd does not continue to work with old data. No stale-data situations here, periodt. 💅

Allowed values for service are passwd, group or hosts.

🌸 RETURN VALUE 🌸

nscd_flush_cache() returns 0 on success. On error, -1 is returned, and errno is set appropriately. So if you see that -1, check errno — she's trying to tell you something. 😭

🎀 ERRORS 🎀

• ENOENT — the nscd daemon is not running.
• EINVAL — service does not contain a valid value.

🫶 NOTES 🫶

Old nscd implementations don't return an error if the service value is invalid. That's the whole note, bestie — no extras, no cap. 🫶
