explain_realpath_or_die(3) Library Functions Manual explain_realpath_or_die(3) NAME explain_realpath_or_die - return canonical pathname and report errors SYNOPSIS #include <libexplain/realpath.h> char *explain_realpath_or_die(const char *pathname, char *resolved_path- name); char *explain_realpath_on_error(const char *pathname, char *resolved_path- name); DESCRIPTION The explain_realpath_or_die function is used to call the realpath(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_realpath(3) function, and then the process terminates by call- ing exit(EXIT_FAILURE). The explain_realpath_on_error function is used to call the realpath(3) sys- tem call. On failure an explanation will be printed to stderr, obtained from the explain_realpath(3) function, but still returns to the caller. pathname The pathname, exactly as to be passed to the realpath(3) system call. resolved_pathname The resolved_pathname, exactly as to be passed to the realpath(3) system call. RETURN VALUE The explain_realpath_or_die function only returns on success, see real- path(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_realpath_on_error function always returns the value return by the wrapped realpath(3) system call.
