$tagOVERLAPPED

Contains information used in asynchronous (or overlapped) input and output (I/O).

Global Const $tagOVERLAPPED = "int Internal;int InternalHigh;int Offset;int OffsetHigh;int hEvent"

 

参数

Internal Reserved for operating system use. This member, which specifies a system-dependent status, is
valid when the GetOverlappedResult function returns without setting the extended error information to
ERROR_IO_PENDING.
InternalHigh Reserved for operating system use. This member, which specifies the length of the data
transferred, is valid when the GetOverlappedResult function returns True.
Offset File position at which to start the transfer. The file position is a byte offset from the start
of the file. The calling process must set this member before calling the ReadFile or WriteFile function. This
member is used only when the device is a file. Otherwise, this member must be zero.
OffsetHigh High-order word of the file position at which to start the transfer. This member is used only
when the device is a file. Otherwise, this member must be zero.
hEvent Handle to an event that will be set to the signaled state when the operation has completed. The
calling process must set this member either to zero or a valid event handle before calling any overlapped
functions.

 

注意/说明

None.
