[Cs-dev] Still attempting to understand the API in Java

Subject	[Cs-dev] Still attempting to understand the API in Java
	I need to use csound->ChanOAGet but the code in java_interface_wrap.cc (Java_csnd_csndJNI_csoundChanOAGet) says CSOUND arg1 = (CSOUND ) 0 ; double arg2 = (double ) 0 ; int arg3 ; int result; arg1 = (CSOUND )&jarg1; arg2 = (double *)&jarg2; arg3 = (int)jarg3; result = (int)csoundChanOAGet(arg1,arg2,arg3); so arg2 is an array of doubles. This is not in accord with the API in H/csoundCore.h int (ChanOAGet)(CSOUND , MYFLT value, int n); unless MYFLT is double. What have I misunderstood? ==John ffitch ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

SWIG probably doesn't even see the MYFLT typedef. Saludos, Felipe Sateler

	Actually, the wrapper file is probaby left over from a prior build. SWIG is configured by SCons with the correct MYFLT definition. A clean and rebuild should fix the problem.
