It is in a header file, otherwise the C compiler will not compile it  
either. According to https://bugzilla.redhat.com/bugzilla/ 
attachment.cgi?id=3380, it may be defined like this in plotter.h:

typedef struct plPlotterParamsStruct
{
   int (*setplparam) (struct plPlotterParamsStruct *_plotter_params,  
const char *parameter, void * value);
   void * plparams[33];
}
PlotterParams;
