vmlGetErrStatus, vmlSetErrStatus, vmlClearErrStatus Get, set, and clear error status for VMATH functions
exception flags, which represent exceptional (error) conditions separately
(see fenv.h), provide a fuller accounting.
Usage VMATH:
#include <vmath.h>
unsigned int vmlGetErrStatus (void) ;
unsigned int vmlSetErrStatus (unsigned int err) ;
unsigned int vmlClearErrStatus (void) ;
VMATH8:
#include <vmath.h>
unsigned int vmlGetErrStatus (void) ;
unsigned int vmlSetErrStatus (unsigned int err) ;
unsigned int vmlClearErrStatus (void) ;
Input err VMATH error status to be set (vmlSetErrStatus).
Output err Current VMATH error status (vmlGetErrStatus)
olderr Pre-call value of VMATH error status
(vmlSetErrStatus, vmlClearErrStatus).
