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_pathname); char *explain_realpath_on_error(const char *pathname, char *resolved_pathname);
DESCRIPTION The explain_realpath_or_die function is used to call the realpath(3) system call. On fail‐ ure an explanation will be printed to stderr, obtained from the explain_realpath(3) func‐ tion, and then the process terminates by calling exit(EXIT_FAILURE). The explain_realpath_on_error 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, 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 realpath(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.
EXAMPLE The explain_realpath_or_die function is intended to be used in a fashion similar to the following example: char *result = explain_realpath_or_die(pathname, resolved_pathname);
