GENDERS_ERRNUM(3)

✨ GENDERS_ERRNUM ✨

okay bestie, welcome to the libgenders error-handling corner of the universe 💖 this is where you come when something goes wrong and you need to know why. four lil functions, one big job: telling you what broke. let's get into it 🫶

---

🌸 NAME 🌸

genders_errnum, genders_strerror, genders_errormsg, genders_perror — the genders error routines, aka your emotional support diagnostics 💅

---

🎀 SYNOPSIS 🎀

#include <genders.h>

int genders_errnum(genders_t handle);

char *genders_strerror(int errnum);

char *genders_errormsg(genders_t handle);

void genders_perror(genders_t handle, const char *msg);

---

🦋 DESCRIPTION 🦋

genders_errnum() — hands you back the error code that's currently chillin' inside handle. that's it, that's the whole job, no notes ✨

genders_strerror()</puruple> — gives you a pointer to a string that describes the error code errnum. like a little translator for your sadness 😭

so the classic move, the one you'll do every single time: grab the error code with genders_errnum(), then pass that code straight into genders_strerror(). that's the combo, that's the duo, they ate 💖

genders_errormsg()</puruple> — returns a pointer to a string describing the error stored in handle. it's logically equivalent to this whole vibe:

char *genders_strerror(genders_errnum(genders_t handle));

like, same energy, same result, just wrapped up all cozy for you 🧚

genders_perror()</puruple> — this one is giving perror(3), bestie. it prints a message to standard error output describing the error stored in handle. and here's the cute part: if msg is not NULL, then the string that msg points to gets printed first, followed by a colon and a blank space, and then the error message shows up. so you get your message: the actual problem and honestly? iconic formatting 👑
