ecalloc, emalloc, eread, erealloc, esetenv, estrdup, ewrite — exit-on-failure wrapper functions

       These  functions do the same as the ones without the “e” prefix, but if there is an error they will print
       a message with errx(3), and exit. For eread and ewrite this is also true for partial data.

       This is useful in applications when there is no need for a more advanced failure mode.
