easprintf(), efopen(),
  ecalloc(), emalloc(),
  erealloc(), ereallocarr(),
  estrdup(), estrndup(),
  estrlcat(), estrlcpy(),
  estrtoi(), estrtou(), and
  evasprintf() functions operate exactly as the
  corresponding functions that do not start with an ‘e’ except
  that in case of an error, they call the installed error handler that can be
  configured with esetfunc().
For the string handling functions, it is an error when the
    destination buffer is not large enough to hold the complete string. For
    functions that allocate memory or open a file, it is an error when they
    would return a null pointer. The default error handler is
    err(3). The function
    esetfunc() returns the previous error handler
    function. A NULL error handler will just call
    exit(3).
estrtoi(), estrtou() and
  ereallocarr() functions were added in
  NetBSD 8.
