int mcal_open ( string calendar, string username, string password [, int options] )
Returns an MCAL stream on success, FALSE on error.
mcal_open() opens up an MCAL connection to the
specified calendar store. If the optional
options is specified, passes the
options to that mailbox also. The streams
internal event structure is also initialized upon connection.
If you get stream connection failures, go back to the libmcal src directory and run 'make install.' On RH6, that builds /usr/local/mcal and drops all the necessary libs. This step wasn't in the mcal HOW-TO (03-12-2000).
