explain_realpath_or_die(3) FreeBSD Library Functions Manual explain_realpath_or_die(3)

explain_realpath_or_die - return canonical pathname and report errors

#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);

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 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.

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.

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);

realpath(3)
return the canonicalized absolute pathname
explain_realpath(3)
explain realpath(3) errors
exit(2)
terminate the calling process
