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.
