| 释义 | WNetGetLastError 语法： C++ DWORD WNetGetLastError( __out LPDWORD lpError, __out LPTSTR lpErrorBuf, __in DWORD nErrorBufSize, __out LPTSTR lpNameBuf, __in DWORD nNameBufSize ); WNetGetLastError功能 该WNetGetLastError函数检索最新的扩展错误代码1 WNet的功能集。该网络供应商举报此错误代码，它不会一般的错误之一Winerror.h中SDK头文件中。 参数 lpError [out] 指针变量，它接收错误代码的网络供应商报告。错误代码是特定于网络提供商。 lpErrorBuf [out] 缓冲区指针接收空结尾的字符串描述错误的。 nErrorBufSize [in] 缓冲区的大小指向的lpErrorBuf参数，以字符。如果缓冲区的内容过于小错误字符串，该字符串被截断，但仍然空终止。为最少256个字符缓冲区的建议。 lpNameBuf [out] 缓冲区指针接收空结尾的字符串识别网络供应商，提高了错误。 nNameBufSize [in] 缓冲区的大小指向的lpNameBuf参数，以字符。如果缓冲区的内容过于小错误字符串，该字符串被截断，但仍然空终止。 返回值 如果函数成功，并获得了最后一个错误，网络提供商报道，返回值为NO_ERROR。 如果调用方提供一个无效的缓冲区，则返回值为ERROR_INVALID_ADDRESS。 备注 该WNetGetLastError函数检索错误所特有的网络提供商。您可以调用WNetGetLastError当WNet函数返回ERROR_EXTENDED_ERROR。 GetLastError函数一样，WNetGetLastError返回扩展的错误信息，这是对每个线程的维修保养。与GetLastError函数，该函数可以返回WNetGetLastError报告是没有任何现有的Winerror.h中描述的错误，错误代码字符串。 有关使用应用程序的信息定义的错误处理程序调用WNetGetLastError功能，请参见检索网络错误。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWinnetwk.h LibraryMpr.lib DLLMpr.dll Unicode和ANSI namesWNetGetLastErrorW(Unicode)和WNetGetLastErrorA(ANSI)的 参见 Windows网络(WNet)概述 Windows网络函数 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年8月6日 ＝＝英文原文＝＝WNetGetLastError Function The WNetGetLastError function retrieves the most recent extended error code set by a WNet function. The network provider reported this error code; it will not generally be one of the errors included in the SDK header file WinError.h. Syntax C++ DWORD WNetGetLastError( __out LPDWORD lpError, __out LPTSTR lpErrorBuf, __in DWORD nErrorBufSize, __out LPTSTR lpNameBuf, __in DWORD nNameBufSize ); Parameters lpError [out] Pointer to a variable that receives the error code reported by the network provider. The error code is specific to the network provider. lpErrorBuf [out] Pointer to the buffer that receives the null-terminated string describing the error. nErrorBufSize [in] Size of the buffer pointed to by the lpErrorBuf parameter, in characters. If the buffer is too small for the error string, the string is truncated but still null-terminated. A buffer of at least 256 characters is recommended. lpNameBuf [out] Pointer to the buffer that receives the null-terminated string identifying the network provider that raised the error. nNameBufSize [in] Size of the buffer pointed to by the lpNameBuf parameter, in characters. If the buffer is too small for the error string, the string is truncated but still null-terminated. Return Value If the function succeeds, and it obtains the last error that the network provider reported, the return value is NO_ERROR. If the caller supplies an invalid buffer, the return value is ERROR_INVALID_ADDRESS. Remarks The WNetGetLastError function retrieves errors that are specific to a network provider. You can call WNetGetLastError when a WNet function returns ERROR_EXTENDED_ERROR. Like the GetLastError function, WNetGetLastError returns extended error information, which is maintained on a per-thread basis. Unlike GetLastError, the WNetGetLastError function can return a string for reporting errors that are not described by any existing error code in WinError.h. For more information about using an application-defined error handler that calls the WNetGetLastError function, see Retrieving Network Errors .
