Handle to an array of 32-bit integers

dtsIntArrayHandles are used to return variable-length integer arrays from certain dtSearch Engine API functions. To obtain the contents of the array:

1. Use dtssIntArrayGetLength to get the length of the array,
2. Allocate a buffer large enough for the array,
3. Call dtssIntArrayGetItems to obtain the contents of the array, and
4. Call dtssIntArrayDelete to free the memory that was allocated for the string.
