[linux-audio-dev] help with multiple control ports

Hello all! I have a problem with creating a plugin with more than one control port. In the attachment you'll find "booster-simple.c" which has one "Gain" port and my attempt to add a second port in "booster.c". For some reason the latter cannot be used - the sources seem to be correct, it compiles fine, but then if I test with "applyplugin" it segfaults and other hosts complain about a malloc() error and hang. Debugging shows that ports are not properly connected: [connectPortToBooster] setting BOOSTER_INPUT1 [connectPortToBooster] setting BOOSTER_OUTPUT1 [runMonoBooster] applyplugin: booster.c:112: runMonoBooster: Assertion `psBooster->m_pfGainValue != 0' failed. ...but I cannot investigate further as my C is very basic. I would really appreciate any help. I based my plugin on the amp.c from the SDK, and I see that in example plugins like simple delay (where there is more than one control port) memory allocation is done differently, but I just don't know how to properly apply these techniques to my plugin... Thanks very much! Artemiy. P.S. I've sent a message with a 50Kb attachment and it's in moderation queue, but these sources are newer.
