VML Service Functions

SetMode sets the VML mode to mode parameter and stores the previous VML mode to oldmode.
Fortran:
oldmode = vmlsetmode( mode ) C:
oldmode = vmlSetMode( mode );

GetMode gets the VML mode.
Fortran:
mod = vmlgetmode() C:
mod = vmlGetMode( void );

SetErrStatus sets the VML error status to err and stores the previous VML error status to olderr.
Fortran:
olderr = vmlseterrstatus( err ) C:
olderr = vmlSetErrStatus( err );

GetErrStatus gets the VML error status.
Fortran:
err = vmlgeterrstatus( ) C:
err = vmlGetErrStatus( void );

ClearErrStatus sets the VML error status to VML_STATUS_OK and stores the previous VML error status to olderr.
Fortran:
olderr = vmlclearerrstatus( ) C:
olderr = vmlClearErrStatus( void );

SetErrorCallBack sets the additional error handler callback function and gets the old callback function.
Fortran:
oldcallback = vmlseterrorcallback( callback ) C:
oldcallback = vmlSetErrorCallBack( callback );

GetErrorCallBack gets the additional error handler callback function.
Fortran:
fun = vmlgeterrorcallback( ) C:
fun = vmlGetErrorCallBack( void );

ClearErrorCallBack deletes the additional error handler callback function and retrieves the former callback function.
Fortran:
oldcallback = vmlclearerrorcallback( ) C:
oldcallback = vmlClearErrorCallBack( void );
