explain_fstatat_or_die(3)

✨ NAME ✨

okay so bestie, this is the explain_fstatat_or_die(3) page from the Library Functions Manual 💖

• explain_fstatat_or_die — get file status relative to a dir fd and report errors ✨

🌸 SYNOPSIS 🌸

#include <libexplain/fstatat.h>
void explain_fstatat_or_die(int fildes, const char *pathname, struct
stat *data, int flags);
int explain_fstatat_on_error(int fildes, const char *pathname, struct
stat *data, int flags);

💖 DESCRIPTION 💖

okay so here's the tea ☕️:

• explain_fstatat_or_die is used to call the fstatat(2) system call. On failure, an explanation will be printed to stderr, obtained from the explain_fstatat(3) function, and then the process terminates by calling exit(EXIT_FAILURE). 💀
• explain_fstatat_on_error is used to call the fstatat(2) system call. On failure, an explanation will be printed to stderr, obtained from the explain_fstatat(3) function, but still returns to the caller. 🫶
• fildes — The fildes, exactly as to be passed to the fstatat(2) system call.
• pathname — The pathname, exactly as to be passed to the fstatat(2) system call.
• data — The data, exactly as to be passed to the fstatat(2) system call.
• flags — The flags, exactly as to be passed to the fstatat(2) system call.

👑 RETURN VALUE 👑

• explain_fstatat_or_die only returns on success, see fstatat(2) for more information. On failure, it prints an explanation and exits, it does not return. 😭
• explain_fstatat_on_error always returns the value return by the wrapped fstatat(2) system call. 💅

🦋 EXAMPLE 🦋

The explain_fstatat_or_die function is intended to be used in a fashion similar to the following example:

explain_fstatat_or_die(fildes, pathname, data, flags);
