PMEM2_PERROR(3)

💖 NAME 💖

okay bestie, meet pmem2_perror() — she prints a descriptive error message to stderr. that's it, that's the whole job, and she does it flawlessly ✨

---

🎀 SYNOPSIS 🎀

#include <libpmem2.h>

void pmem2_perror(const char *format, ...);

---

🌸 DESCRIPTION 🌸

so here's the tea: the pmem2_perror() function drops a message onto the standard error stream, and that message describes the last error encountered during a library call. like, she's your little bestie who remembers what went wrong so you don't have to 🫶

she takes a variable number of arguments. first up, the argument string format gets printed — similarly to what printf(3) does — and then right after it comes a colon and a blank. then she pulls in the error message she got from pmem2_errormsg(), and finally a new-line to wrap the whole thing up cute 💅

curious how that error message actually gets generated? go peek at pmem2_errormsg(3), she explains everything 👑
