14.24. Slapi_MatchingRuleEntry

Slapi_MatchingRuleEntry is the data type for an opaque structure that represents a matching rule.
The matching rule definition can be specified as a dynamic declaration using functions such as slapi_matchingrule_new() or slapi_matchingrule_set().
Alternatively, the matching rule definition can also be specified as a static declaration. For example: 
static Slapi_MatchingRuleEntry
integerMatch = { INTEGERMATCH_OID, NULL /* no alias? */,
	"integerMatch", "The rule evaluates to TRUE if and only if the
attribute value and the assertion value are the same integer value.",
	INTEGER_SYNTAX_OID, 0 /* not obsolete */ };
...
int
int_init( Slapi_PBlock *pb )
{
	int rc;
...
	rc = slapi_matchingrule_register(&integerMatch);
...
}
