NAME¶

ecalloc, emalloc, eread, erealloc, esetenv, estrdup, ewrite —

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.
