MClock Intrinsic
................

     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.  Therefore,
the values returned by this intrinsic might be, or become, negative, or
numerically less than previous values, during a single run of the
compiled program.

   Note: 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.
