NAME

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

LIBRARY

       The roken library (libroken, -lroken)

SYNOPSIS

       #include <roken.h>

       void *
       ecalloc(size_t number, size_t size);

       void *
       emalloc(size_t sz);

       ssize_t
       eread(int fd, void *buf, size_t nbytes);

       void *
       erealloc(void *ptr, size_t sz);

       void
       esetenv(const char *var, const char *val, int rewrite);

       char *
       estrdup(const char *str);

       ssize_t
       ewrite(int fd, const void *buf, size_t nbytes);

DESCRIPTION

       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.
