IMSL Functions: C vs Fortran

[nyckmaia]

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,

I think that you have misunderstood the conventions in the IMSL Fortran library. LINRG_INT is not the name of a Fortran subprogram; it is the interface to the subprogram LINRG (which is a generic name that may be resolved into a call to LINRG, DLINRG, S_LINRG or D_LINRG).

For questions such as these, I can't think of a reason not to consult the published and easily accessible IMSL documentation, which is also well-written and nicely formatted.
