顺便说一句，如果另一端从中读取数据，剩余缓冲区会自动增加，对吗？ 最佳答案 PeekNamedPipe怎么样？？似乎以下将返回要从管道中读取的剩余字节总数。DWORDtotalBytesAvailable;BOOLWINAPIPeekNamedPipe(handle,//__inHANDLEhNamedPipe,NULL,//__out_optLPVOIDlpBuffer,0,//__inDWORDnBufferSize,NULL,//__out_optLPDWORDlpBytesRead,&totalBytesAvailable,

hPipe=CreateNamedPipe(lpszPipename,//pipenamePIPE_ACCESS_DUPLEX,//read/writeaccessPIPE_TYPE_MESSAGE|//messagetypepipePIPE_READMODE_MESSAGE|//message-readmodePIPE_WAIT,//blockingmodePIPE_UNLIMITED_INSTANCES,//max.instances100,//outputbuffersize100,//inputbuffersize0,//clienttime-outNULL);//defaul

PeekNamedPipe(tmp_pipe,//__inHANDLEhNamedPipe,NULL,//__out_optLPVOIDlpBuffer,0,//__inDWORDnBufferSize,NULL,//__out_optLPDWORDlpBytesRead,&totalBytesAvailable,//__out_optLPDWORDlpTotalBytesAvail,NULL//__out_optLPDWORDlpBytesLeftThisMessage);我已将字节写入其他地方的管道，但totalBytesAvailable始终为0，为什么？
