Application software calls the GetNumAudioOutBuffers API procedure to determine how many audio output line buffers are available for use.

Namespace:  LanScape
Assembly:  LMEVoipManaged (in LMEVoipManaged.dll) Version: 6.0.5226.26700

Syntax

C#
public VoipMediaEngine..::.TELEPHONY_RETURN_VALUE GetNumAudioOutBuffers(
	ref int NumAudioOutBuffers
)
Visual Basic (Declaration)
Public Function GetNumAudioOutBuffers ( _
	ByRef NumAudioOutBuffers As Integer _
) As VoipMediaEngine..::.TELEPHONY_RETURN_VALUE
Visual C++
public:
VoipMediaEngine..::.TELEPHONY_RETURN_VALUE GetNumAudioOutBuffers(
	int% NumAudioOutBuffers
)
J#
public VoipMediaEngine..::.TELEPHONY_RETURN_VALUE GetNumAudioOutBuffers(
	/** @ref */int NumAudioOutBuffers
)

Parameters

NumAudioOutBuffers
Type: System..::.Int32 %
A reference to an integer variable that will receive the number of audio output line buffers that are available for use.

Return Value

If the function succeeds, the return value will be SipSuccess.

If the function fails, the return value will be one of the following values as specified by the VoipMediaEngine..::.TELEPHONY_RETURN_VALUE data type.

Return ValueDescription
SipCallFailure
This value is returned by telephony API procedures to indicate general API failure. This error value is used as a "catch all error". If you receive this error, check to make sure that all parameters specified in the API procedure call are correct. Particularly, verify that pointers to memory regions are valid. This error return value is only used if a mapping to another specific error value does not exist.

(API return value)

SipBadParameter
One of the telephony API procedures was called by application software and was passed a pointer to an invalid memory address. Normally this error will occur when application software passes NULL pointer values to the telephony API. For managed code applications, you should never see this error unless your process space has exhausted memory.

(API return value)

SipInvalidHandle
Application software specified an invalid telephony handle in one of the API procedures. This usually indicates memory corruption on the part of application software.
