uiFindRule()

aint uiFindRule	(	semantic_rule *	spRules,
		aint	uiRuleCount,
		const char *	cpName,
		aint	uiNameLength
	)

[in]	cpName	- pointer to the name to look for (not a null-terminated string)
[in]	uiNameLength	- the number of characters in the name

Returns

the index of the rule in the rule list if the name is found, APG_UNDEFINED otherwise
