In C, this function returns a pointer to a structure containing information about the hardware on which the program runs. In Fortran, the values of the structure are returned explicitly.
- Return values

- If called before initialization the behavior of the routine is undefined.

- The C structure contains detailed information about cache and TLB sizes. This information is not available from Fortran.
