NAME
ecalloc, emalloc, eread, erealloc, esetenv, estrdup, ewrite ā 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 āeā 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.
