AUSEARCH_ADD_REGEX(3) Linux Audit API AUSEARCH_ADD_REGEX(3)

SYNOPSIS
#include <auparse.h>
int ausearch_add_regex(auparse_state_t *au, const char *expr);
DESCRIPTION

to scan logs, files, or buffers for something of interest. You may not use this in combination with any other search expression. The regu-
lar expression follows the posix regular expression conventions. The search results are at the record level and not the field.
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).
