NAME explain_linkat_or_die - link a file relative to directory and report errors
SYNOPSIS #include <libexplain/linkat.h> void explain_linkat_or_die(int old_dirfd, const char *old_path, int new_fildes, const char *new_path, int flags); int explain_linkat_on_error(int old_dirfd, const char *old_path, int new_fildes, const char *new_path, int flags);
DESCRIPTION The explain_linkat_or_die function is used to call the linkat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_linkat(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_linkat_on_error function is used to call the linkat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_linkat(3) function, but still returns to the caller. old_dirfd The old_dirfd, exactly as to be passed to the linkat(2) system call. old_path The old_path, exactly as to be passed to the linkat(2) system call. new_fildes The new_fildes, exactly as to be passed to the linkat(2) system call. new_path The new_path, exactly as to be passed to the linkat(2) system call. flags The flags, exactly as to be passed to the linkat(2) system call.
RETURN VALUE The explain_linkat_or_die function only returns on success, see linkat(2) for more infor‐ mation. On failure, prints an explanation and exits, it does not return. The explain_linkat_on_error function always returns the value return by the wrapped linkat(2) system call.
EXAMPLE The explain_linkat_or_die function is intended to be used in a fashion similar to the fol‐ lowing example: explain_linkat_or_die(old_dirfd, old_path, new_fildes, new_path, flags);
