QB_LOG_FILE_OPEN(3)

✨ NAME ✨

qb_log_file_open — open a log file. 💖 Like, that's literally the whole vibe bestie, no cap. It opens a log file. Slay.

---

🌸 SYNOPSIS 🌸

Okay so here's the exact fit, copy it character for character or it's not gonna hit:

#include <qb/qblog.h>

int32_t qb_log_file_open(
    const char   *filename
);

One argument, one dream: filename is a const char *. That's it. That's the whole signature. 🦋

💅 DESCRIPTION 💅

Not me noticing the DESCRIPTION section is literally empty in the original manpage… 😭 Bestie the authors really said "figure it out" and left this part blank. No shade, it's giving minimalist. The NAME section already told you the whole plot though: this function opens a log file. Periodt. 💅

🫶 RETURN VALUE 🫶

Here's what you get back, and you better check it:

• -errno — this is what you get on error. Negative errno, so like, if it's negative, something went sideways, bestie. 🙈
• a value in the inclusive range QB_LOG_TARGET_DYNAMIC_START to QB_LOG_TARGET_DYNAMIC_END — this is the good outcome ✨ and it's meant to be passed into other qb_log_* functions, so hold onto it, it's your lil ticket. 🎀
