NAME

       ausearch_add_regex - use regular expression search rule

SYNOPSIS

       #include <auparse.h>

       int ausearch_add_regex(auparse_state_t *au, const char *expr);

DESCRIPTION

       ausearch_add_regex  adds  one  search condition based on a regular expression to the current audit search expression. The search conditions
       can then be used to scan logs, files, or buffers for something of interest. The regular	expression  follows  the  posix  extended  regular
       expression conventions, and is matched against the full record (without interpreting field values).

       If an existing search expression E is already defined, this function replaces it by (E && this_regexp).

RETURN VALUE

       Returns -1 if an error occurs; otherwise, 0 for success.
