RXS_getBuffLen()

Use this subprocedure to retrieve the length of data that has buffered in the Template Engine. Note that RXS_VAR should have been specified for the pOutType parameter on the call to RXS_initTplEng() API for this to work. This is most often used in conjunction with RXS_getUri() where RXS_getBuffData() is used to obtain the current data stored in the template engine.
