IltmmWMProfile::CreateNewMutualExclusion
#include "ltmm.h"
C Syntax |
HRESULT IltmmWMProfile_CreateNewMutualExclusion(pProfile, pVal) |
C++ Syntax |
HRESULT CreateNewMutualExclusion(pVal) |
IltmmWMProfile *pProfile; |
/* pointer to an interface */ |
IltmmWMMutualExclusion **pVal; |
/* pointer to a pointer */ |
Creates a mutual exclusion object. The mutual exclusion objects are used to specify a number of mutually exclusive streams. This means that only one stream can be used or delivered at a time.
Parameter |
Description |
pProfile |
Pointer to an IltmmWMProfile interface. |
pVal |
Pointer to a variable to be updated with a pointer to the IltmmWMMutualExclusion interface of the created object. |
Returns
S_OK |
The function was successful. |
<> S_OK |
An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation. |
Comments
The ltmmWMMutualExclusion object is not externally creatable; it can only be accessed through the IltmmWMMutualExclusion interface referenced by pVal. If the method succeeds, the caller must free the retrieved interface by calling its Release method.
Please note that creating a new mutual exclusion object does not automatically add it to the profile. The new mutual exclusion object must be created using IltmmWMProfile::CreateNewMutualExclusion, and then configured using the IltmmWMMutualExclusion interface. The configured mutual exclusion object must then be added to the profile using IltmmWMProfile::AddMutualExclusion.
