EcOpenSubscription function (evcoll.h)
The EcOpenSubscription function is used to open an existing subscription or create a new subscription according to the flag value specified.
Syntax
EC_HANDLE EcOpenSubscription(
[in] LPCWSTR SubscriptionName,
[in] DWORD AccessMask,
[in] DWORD Flags
);
Parameters
[in] SubscriptionName
Specifies the name of the subscription. The value provided for this parameter should be unique within the computer's scope.
[in] AccessMask
An access mask that specifies the desired access rights to the subscription. Use the EC_READ_ACCESS or EC_WRITE_ACCESS constants to specify the access rights. The function fails if the security descriptor of the subscription does not permit the requested access for the calling process.
[in] Flags
A value specifying whether a new or existing subscription will be opened. Use the EC_CREATE_NEW, EC_OPEN_ALWAYS, or EC_OPEN_EXISTING constants.
Return value
If the function succeeds, it returns a handle (EC_HANDLE) to a new subscription object. Returns NULL otherwise, in which case use the GetLastError function to obtain the error code.
