cgGetNumProgramDomains - get the number of domains in a combined program

SYNOPSIS
  #include <Cg/cg.h>
  int cgGetNumProgramDomains( CGprogram program );

PARAMETERS
The combined program object to be queried.

RETURN VALUES
Returns the number of domains in the combined program program.

cgGetNumProgramDomains will always return 1 for a non-combined program.

EXAMPLES
  CGprogram combined = cgCombinePrograms2( prog1, prog2 );
  int numDomains = cgGetNumProgramDomains( combined );
  /* numDomains == 2 */

ERRORS
CG_INVALID_PROGRAM_HANDLE_ERROR is generated if program is not a valid program handle.
