lineopen(),linemakecall( )的返回值是什么？

[samp_miao]

LONG lineMakeCall(
HLINE hLine,
LPHCALL lphCall,
LPCWSTR lpszDestAddress,
DWORD dwCountryCode,
LPLINECALLPARAMS const lpCallParams
);
Return Values
A positive request identifier indicates that the function is completed asynchronously. A negative error number indicates that an error has occurred. The dwParam2 parameter of the corresponding LINE_REPLY message is zero if the function succeeds, or it is a negative error number if an error occurs. The following table shows the return values for this function.

Value Description
LINEERR_ADDRESSBLOCKED The address is blocked
LINEERR_BEARERMODEUNAVAIL The bearer mode member in LINECALLPARAMS is invalid, the bearer mode specified in LINECALLPARAMS is not available, or the call's bearer mode cannot be changed to the specified bearer mode.
LINEERR_CALLUNAVAIL The call is unavailable.
LINEERR_DIALBILLING The dialable address parameter contains dialing control characters that are not processed by the service provider.
LINEERR_DIALDIALTONE The dialable address parameter contains dialing control characters that are not processed by the service provider.
LINEERR_DIALPROMPT The dialable address parameter contains dialing control characters that are not processed by the service provider.
LINEERR_DIALQUIET The dialable address parameter contains dialing control characters that are not processed by the service provider.
LINEERR_INUSE The line is in use.
LINEERR_INVALADDRESS The address is invalid.
LINEERR_INVALADDRESSID The address id is invalid.
LINEERR_INVALADDRESSMODE The address mode is invalid.
LINEERR_INVALBEARERMODE The bearer mode is invalid.
LINEERR_INVALCALLPARAMS Invalid parameters used for this call.
LINEERR_INVALCOUNTRYCODE The country/region code provided was invalid.
LINEERR_INVALLINEHANDLE The line handle is invalid.
LINEERR_INVALLINESTATE The line is not in a state such that this operation can be performed.
LINEERR_INVALMEDIAMODE The media mode is invalid.
LINEERR_INVALPARAM The parameters are invalid.
LINEERR_INVALPOINTER The pointer is invalid.
LINEERR_INVALRATE The rate is invalid.
LINEERR_NOMEM The operation requires more memory than is currently available.
LINEERR_OPERATIONFAILED The operation failed.
LINEERR_OPERATIONUNAVAIL The operation is unavailable.
LINEERR_RATEUNAVAIL The rate is unavailable.
LINEERR_RESOURCEUNAVAIL The resource is unavailable.
LINEERR_STRUCTURETOOSMALL The structure is too small.
LINEERR_UNINITIALIZED The parameter is uninitialized.
LINEERR_USERUSERINFOTOOBIG The users information is too large.

LONG lineOpen(
HLINEAPP hLineApp,
DWORD dwDeviceID,
LPHLINE lphLine,
DWORD dwAPIVersion,
DWORD dwExtVersion,
DWORD dwCallbackInstance,
DWORD dwPrivileges,
DWORD dwMediaModes,
LPLINECALLPARAMS const lpCallParams
);

Return Values
Zero indicates success. A negative error number indicates that an error occurred. The following table shows the return values for this function.

Value Description
LINEERR_ALLOCATED The line cannot be opened due to a persistent condition.
LINEERR_BADDEVICEID The device id provided is incorrect.
LINEERR_INCOMPATIBLEAPIVERSION The API version is incompatible
LINEERR_INCOMPATIBLEEXTVERSION The extension version is incompatible.
LINEERR_INVALAPPHANDLE The app handle is invalid.
LINEERR_INVALMEDIAMODE The line device is opened with owner privilege and an extension media mode is not registered.
LINEERR_INVALPOINTER The pointer is invalid.
LINEERR_INVALPRIVSELECT The privilege selected is invalid.
LINEERR_LINEMAPPERFAILED
LINEERR_NODEVICE The device was not found.
LINEERR_NODRIVER The driver was not found.
LINEERR_NOMEM Not enough memory is available for this operation.
LINEERR_OPERATIONFAILED The operation failed.
LINEERR_OPERATIONUNAVAIL The operation is unavailable.
LINEERR_REINIT The application attempted to initialize TAPI twice.
LINEERR_RESOURCEUNAVAIL The line cannot be opened due to a dynamic resource overcommitment
LINEERR_STRUCTURETOOSMALL The structure is too small.
LINEERR_UNINITIALIZED A parameter is uninitialized.




看SDK 啊。。。。。。

如果是用Modem设备，使用模拟电话线路，试图准确判断外拨结果，的确是困难的。好一点的能够判断出忙音。
有些软件的想法有特点，只要拨号完毕就认为接通，然后开始录音，根据录下的信号音判断什么信号。当然在编程上比较复杂。

其实很多应用都是通知、催缴、广告一类，未必要求那么高，多播放几次语音就可以了。
也可以要求对方按键确认，超时后就挂断，下次再来。

专业的模拟语音卡通常都可以设置信号音参数，相对准确，但对于对方是手机的情况，如彩铃之类，也不是那么准确。
最准确的是采用数字线路接口的数字语音卡，通常使用ISDN或7号信令，但价格较高。

采用微软的TAPI3，编程比较烦琐。可以下载我的免费平台，那就只要写几行类似C语言的脚本就可以了：
