FtVspcCreatePortOverlappedEx Function

Custom license key is needed to unlock this function. Otherwise it fails.

BOOL FtVspcCreatePortOverlappedEx(
	LPCTSTR lpszPortName,
	LPCTSTR lpszRealPortAlias,
	LPCTSTR lpszFriendlyName,
	LPCTSTR lpszCompanyName 
	);

Parameters

lpszPortName

[in] The name of virtual serial port (e.g. "COM1", "VSP25", "SERPORT10" etc). Names "COM0", "COM4294967295" and "LPTx" are prohibited.
It is recommended to use FtVspcCreatePortOverlappedByNum function for creating virtual serial ports with custom names (e.g. COMx).

lpszCompanyName

[in] Company name. If NULL - the value integrated into the license key is used. Can be set only if any FriendlyName is integrated into the key, otherwise it fails with ftvspcErrorInvalidLicense error.
