* Please note that the following implementation of Windows NT named pipe
|
|
||||||
* support functions is only a partial implementation of these functions.
|
|
||||||
* This is only a wrapping of these functions to enable existing NT code
|
|
||||||
* to function properly. This code should be studied and modified if
|
|
||||||
* necessary when any new calls to these functions are made. In other
|
|
||||||
* words, use these functions within Windows 3.11 at your own risk.
|
|
||||||
* In addition, unlike Windows NT, the error code is reset after each
|
|
||||||
* function call to avoid instancing problems. This means GetLastError()
|
|
||||||
* returns NO_ERROR after a successful function call even if the preceding
|
|
||||||
* function resulted in an error.
