| Summary | 0000874: Special timeout case on reading not handled correctly. | ||||
| Description | There is a special timeout combination available that is documented in the COMMTIMEOUTS description (http://msdn.microsoft.com/en-us/library/aa363190(VS.85).aspx) => see additional information This timeout was not handled in the COM_Read() function. The problem appeared when using the BaseStream class to read data. | ||||
| Additional Information | If an application sets ReadIntervalTimeout and ReadTotalTimeoutMultiplier to MAXDWORD and sets ReadTotalTimeoutConstant to a value greater than zero and less than MAXDWORD, one of the following occurs when the ReadFile function is called: * If there are any bytes in the input buffer, ReadFile returns immediately with the bytes in the buffer. * If there are no bytes in the input buffer, ReadFile waits until a byte arrives and then returns immediately. * If no bytes arrive within the time specified by ReadTotalTimeoutConstant, ReadFile times out. | ||||
