Function name: CreatePipe

Defined in : Kernel32

Requirements : Windows NT 3.1 or later; Windows 95 or later

Declaration:

Declare Function CreatePipe Lib "kernel32" (phReadPipe As Long, phWritePipe As Long, lpPipeAttributes As SECURITY_ATTRIBUTES, ByVal nSize As Long) As Long

Parameters:

* hReadPipe [out] Pointer to a variable that receives the read handle for the pipe. * hWritePipe [out] Pointer to a variable that receives the write handle for the pipe. * lpPipeAttributes [in] Pointer to a structure that determines whether the returned handle can be inherited by child processes. If lpPipeAttributes is NULL, the handle cannot be inherited. Windows NT/2000: The lpSecurityDescriptor member of the structure specifies a security descriptor for the new pipe. If lpPipeAttributes is NULL, the pipe gets a default security descriptor. * nSize [in] Specifies the buffer size for the pipe, in bytes. The size is only a suggestion; the system uses the value to calculate an appropriate buffering mechanism. If this parameter is zero, the system uses the default buffer size.

Returns:

If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError.
