The GetPackageExpiration function returns the number of days that the package can be applied.

BOOL GetPackageExpiration(
	HPACKAGE hPackage,		// handle to package file
	LPDWORD lpdwExpires		// expiration period
);

Parameters

hPackage

[in] Handle to an open package file.

 

lpdwExpires

[out] A pointer to a DWORD value which will contain the number of days before the package expires. A value of zero specifies that the package will never expire.

Return Values

If the GetPackageExpiration function succeeds, it will return a non-zero value.

If the function fails, it will return a value of zero. To get extended error information, call GetLastError.

Remarks

Once a package has expired, it cannot be opened or applied on a target system. Along with protecting the package with a password, this provides a mechanism for controlling the distribution of the package.
