// Function: ArrayToPointer
//
// Description: Converts an InstallShield array into a C array.
//
// When an array is created in InstallScript, a VARIANT variable
// is created which holds an OLEAutomation SAFEARRAY. To pass
// such an array to a DLL function expecting a C-style array,
// this function explicitly typecasts the pointer to the array
// to a _VARIANT pointer so that the _SAFEARRAY pointer can be
// extracted. The pointer to the actual data is then extracted
// from the _SAFEARRAY pointer.
//
// Parameters: structArray - Array variable.
//
// Returns: POINTER - Pointer to array.
