MClock()
MClock: INTEGER(KIND=1) function.
Intrinsic groups: unix.
Description:
Returns the number of clock ticks since the start of the process.
Supported on systems with clock(3) (q.v.).
This intrinsic is not fully portable, such as to systems
with 32-bit INTEGER types but supporting times
wider than 32 bits.
See section MClock8 Intrinsic, for information on a
similar intrinsic that might be portable to more
GNU Fortran implementations, though to fewer
Fortran compilers.
If the system does not support clock(3),
-1 is returned.
