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).
If successful, ausearch_add_expression returns 0. Otherwise, it returns -1, sets errno and it may set *error to an error message; 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.
