I saw both IMSL C and Fortran Library documentation here

But apparently several functions in the Fortran library are not present in the C library.
Example:

| Fortran | C |
| LINRG_INT | function name ? |
| LINCG_INT | function name ? |
| UMACH_INT | function name ? |
| IVPRK_INT | function name ? |
| EVCCG_INT | function name ? |
| EVLCG_INT | function name ? |

and others....

Question 1:
Considering all the functions of the Fortran library, would each of these functions correspond to one of the C library functions?

Question 2:
If yes, Could you give me an example of correspondence using any item from the list above?

Thank you,
