209fcecf507SKris Buschelman     CHKERRQ(n) is fundamentally a macro replacement for
2105324ea47SKris Buschelman          if (n) return(PetscError(...,n,...));
2115324ea47SKris Buschelman 
2125324ea47SKris Buschelman     Although typical usage resembles "void CHKERRQ(PetscErrorCode)" as described above, for certain uses it is
2135324ea47SKris Buschelman     highly inappropriate to use it in this manner as it invokes return(PetscErrorCode). In particular,
2145324ea47SKris Buschelman     it cannot be used in functions which return(void) or any other datatype.  In these types of functions,
215fcecf507SKris Buschelman     a more appropriate construct for using PETSc Error Handling would be
2165324ea47SKris Buschelman          if (n) {PetscError(....); return(YourReturnType);}
