The following is an example of using FNC_GetArrayNumDimensions to retrieve the number of dimensions in an ARRAY type.

This example is based on the following n-D ARRAY definition:

CREATE TYPE myArray AS INTEGER ARRAY[1:20][1:20];

void getNumAryDims ( ARRAY_HANDLE  *phone_ary,
                     INTEGER       *result,
                     char           sqlstate[6])
{
    int numDimensions;
    /* Get the number of dimensions the array is defined with. */
    FNC_GetArrayNumDimensions((*phone_ary), &numDimensions);
    *result = numDimensions;
    ...
}
