- SSYYSSCCLLOOCCKK returns the same real-time clock count returned by the _c_o_u_n_t
- argument to the Fortran 90 SSYYSSTTEEMM__CCLLOOCCKK intrinsic subroutine.
-
- On systems with default 32-bit integer data type, the real-time clock
- value for SSYYSSTTEEMM__CCLLOOCCKK reaches _c_o_u_n_t__m_a_x and wraps around to 0
- occasionally. The number of times that the clock has wrapped is
- returned in _i_w_r_a_p. By using _i_w_r_a_p, you can reliably time intervals
- during which the clock may have wrapped one or more times.
-
- Use the _c_o_u_n_t__r_a_t_e argument on the SSYYSSTTEEMM__CCLLOOCCKK intrinsic subroutine
- to determine the clock rate for SSYYSSCCLLOOCCKK.
-
- When using the CF90 compiler on UNICOS or UNICOS/mk system, all
- arguments must be of default kind unless documented otherwise. On
- UNICOS and UNICOS/mk, default kind is KKIINNDD==88 for integer, real,
- complex, and logical arguments.

- _i_w_r_a_p always returns 0 on 64-bit systems.
