Function Documentation

EXTERNRT void rtxFreeRegexpCache

(

OSCTXT *

pctxt

)

This function frees the memory associated with the regular expression cache.

The regular expression cache is designed to use memory that survives calls to rtxMemFree and rtxMemReset, therefore it is necessary to call this function to free that memory. (Note that rtxFreeContext invokes this.)

EXTERNRT OSBOOL rtxMatchPattern	(	OSCTXT *	pctxt,
		const OSUTF8CHAR *	text,
		const OSUTF8CHAR *	pattern
	)

This function compares the given string to the given pattern.

It returns true if match, false otherwise.

Parameters:

	pctxt	Pointer to context structure.
	text	Text to be matched.
	pattern	Regular expression.

Returns:

Boolean result.
