AUSEARCH_ADD_EXPRESSION(3) Linux Audit API AUSEARCH_ADD_EXPRESSION(3)
ausearch_add_expression - build up search expression
#include <auparse.h>
int ausearch_add_expression(auparse_state_t *au, const char *expression, char **error, ausearch_rule_t how);"
ausearch_add_item adds an 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 expression
parameter contains an expression, as specified in
ausearch-expression(5). The how parameter determines how this
search expression will affect the existing search expression, if
one is already defined. The possible values are:
AUSEARCH_RULE_CLEAR
Clear the current search expression, if any, and use
only this search expression.
AUSEARCH_RULE_OR
If a search expression E is already configured,
replace it by (E || this_search_expression).
AUSEARCH_RULE_AND
If a search expression E is already configured,
replace it by (E && this_search_expression).
The caller must free the error message using free(3). If an error
message is not available or can not be allocated, *error is set to
NULL.
