// 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.
