vmlgeterrstatus, vmlseterrstatus, vmlclearerrstatus Get, set, and clear error status for VMATH library functions
exception flags, which represent exceptional (error) conditions separately
(see fenv.h), provide a fuller accounting.
Usage INTEGER (KIND=4), FUNCTION vmlgeterrstatus( )
INTEGER (KIND=4), FUNCTION vmlseterrstatus(err)
INTEGER (KIND=4) , INTENT (IN) : : err
INTEGER (KIND=4), FUNCTION vmlclearerrstatus( )
The Fortran include file vmath.fi declares interfaces for these functions and
defines the parameters described above.
Input err VMATH error status to be set (vmlseterrstatus).
Output olderr Pre-call value of VMATH error status (vmlseterrstatus,
vmlclearerrstatus).
