/* header file for nagios plugins utils.c */
/* this file should be included in all plugins */
/* The purpose of this package is to provide safer alternantives to C
functions that might otherwise be vulnerable to hacking. This
currently includes a standard suite of validation routines to be sure
that an string argument acually converts to its intended type and a
suite of string handling routine that do their own memory management
in order to resist overflow attacks. In addition, a few functions are
provided to standardize version and error reporting accross the entire
suite of plugins. */
