IsMVcellRepr - test if a value is missing value
SYNOPSIS
#include "csf.h"
int IsMVcellRepr
(
CSF_CR cellRepr,
const void *cellValue
);
PARAMETERS
-
CSF_CR cellRepr
-
cell representation of argument cellValue.
That is one of the constants prefixed by CR_.
Possible values for a
CSF_CR
are as follows:
* preferred version 2 cell representations
- CR_UINT1 - Boolean, ldd and small nominal and small ordinal.
- CR_INT4 - Large nominal and large ordinal.
- CR_REAL4 - Single scalar and single directional.
* other version 2 cell representations
- CR_REAL8 - Double scalar or directional, and also the only type that
can hold all
cell representation without loss of precision.
* version 1 cell representations
these can be returned by BUT NOT passed to a csf2 function
- CR_INT1 -
.
- CR_INT2 -
.
- CR_UINT2 -
.
- CR_UINT4 -
.
* this one CANNOT be returned by NOR passed to a csf2 function
- CR_UNDEFINED - Just some value different from the rest.
-
const void *cellValue
-
value to be tested
