ausearch_add_regex
AUSEARCH_ADD_REGEX(3) Linux Audit API AUSEARCH_ADD_REGEX(3)
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.
SEE ALSO
ausearch_add_expression(3), ausearch_add_item(3), ausearch_clear(3), ausearch_next_event(3), regcomp(3).
