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.

For more information, refer to the Microsoft documentation for IWMProfile::CreateNewMutualExclusion .
