In the case of failure you should free the memory occupied by the engine with <code>cl_free</code>: <PRE> int cl_build(struct cl_engine *engine); void cl_free(struct cl_engine *engine); </PRE> In our example: <PRE> if((ret = cl_build(engine))) { printf("cl_build() error: %s\n", cl_strerror(ret)); cl_free(engine); exit(1); } </PRE> <P> <BR><HR> <ADDRESS> Tomasz Kojm 2007-07-11 </ADDRESS> </BODY> </HTML>
