NAME
     clSetErrorHandler - Select an alternate error handling routine

SYNOPSIS
     #include <dmedia/cl.h>

     CLerrFunc clSetErrorHandler(CLerrFunc efunc)

ARGUMENTS
     efunc  A pointer to an error handling routine declared as
	    void ErrorFunc(CLhandle handle, int code, const char *format, ...)

DESCRIPTION
     clSetErrorHandler allows overriding of the Compression Library's default
     error handling routine, which prints a message to stderr.

     The arguments that are passed to the error handling routine are a handle
     to the processing object, an error code, and a printf-like string
     optionally followed with printf-like arguments.

     The error codes are listed in <dmedia/cl.h>.

RETURN VALUE
     clSetErrorHandler returns a pointer to the previous error handling
     routine.

EXAMPLE
	  #include <dmedia/cl.h>

	  CLerrFunc originalErrorHandler;
	   ...
	  void silentCLError(CLhandle handle, int code, const char* format, ...)
	  {
	       /* ignore all CL errors */
	  }
	   ...
	  originalErrorHandler = clSetErrorHandler(silentCLError);
	  /* CL errors here will go unnoticed */
	   ...
	  clSetErrorHandler(originalErrorHandler);
	  /* back to normal reporting of CL errors */
	   ...
