Routine Description:
|
|
The CreatePipeEx API is used to create an anonymous pipe I/O device.
|
|
Unlike CreatePipe FILE_FLAG_OVERLAPPED may be specified for one or
|
|
both handles.
|
|
Two handles to the device are created. One handle is opened for
|
|
reading and the other is opened for writing. These handles may be
|
|
used in subsequent calls to ReadFile and WriteFile to transmit data
|
|
through the pipe.
|
|
Arguments:
|
|
lpReadPipe - Returns a handle to the read side of the pipe. Data
|
|
may be read from the pipe by specifying this handle value in a
|
|
subsequent call to ReadFile.
|
|
lpWritePipe - Returns a handle to the write side of the pipe. Data
|
|
may be written to the pipe by specifying this handle value in a
|
|
subsequent call to WriteFile.
|
|
lpPipeAttributes - An optional parameter that may be used to specify
|
|
the attributes of the new pipe. If the parameter is not
|
|
specified, then the pipe is created without a security
|
|
descriptor, and the resulting handles are not inherited on
|
|
process creation. Otherwise, the optional security attributes
|
|
are used on the pipe, and the inherit handles flag effects both
|
|
pipe handles.
|
|
nSize - Supplies the requested buffer size for the pipe. This is
|
|
only a suggestion and is used by the operating system to
|
|
calculate an appropriate buffering mechanism. A value of zero
|
|
indicates that the system is to choose the default buffering
|
|
scheme.
|
|
Return Value:
|
|
TRUE - The operation was successful.
|
|
FALSE/NULL - The operation failed. Extended error status is available
|
|
using GetLastError.
