Declare Function CreatePipe Lib "kernel32" (phReadPipe As Long, phWritePipe As Long, lpPipeAttributes As SECURITY_ATTRIBUTES, ByVal nSize As Long) As Long |
|
Operating Systems Supported |
|
Requires Windows NT 3.1 or later; Requires Windows 95 or later |
- 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. |
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. |
