print timing consuming of function pFun 
== long long *nargs ==
Input, number of arguments pFun take.
== void* pFun ==
Input, void function pFun with nargs arguments, all of the args should be pointers.
== ... ==
Input, following  nargs pointer arguments.

= example (Fortran)=
{{{
extern:: dsygst

its original form is
{{{
