WaitForSingleObject (coredll)

coredll is for smart devices, not desktop Windows. Therefore, this information only applies to code using the .NET Compact Framework. To see if information for WaitForSingleObject in other DLLs exists, click on Find References to the right.

WaitForSingleObject- waits on a single kernel object.

C# Signature:

[DllImport("coredll.dll", SetLastError=true)]
public static extern Int32 WaitForSingleObject(IntPtr Handle,Int32 Wait);

public const Int32 INFINITE = -1;
public const Int32 WAIT_ABANDONED = 0x80;
public const Int32 WAIT_OBJECT_0 = 0x00;
public const Int32 WAIT_TIMEOUT = 0x102;
public const Int32 WAIT_FAILED = -1;

VB Signature:

<DllImport("coredll.dll", SetLastError:=True, ExactSpelling:=True)> _
Public Function WaitForSingleObject(ByVal handle As IntPtr, ByVal milliseconds As Integer) As Integer
End Function

Tips & Tricks:

Please add some!

Sample Code:

Both of the below examples assume that pi is an instnace of a ProcessInfo class. Examples of the ProcessInfo class can be found on the CreateProcess page.


int WAIT_OBJECT_0 = 0;
int waitResult = 0;
waitResult = WaitForSingleObject(pi.hProcess,INFINITE);


Dim WAIT_OBJECT_0 As Int32 = 0
Dim result As Int32
result = WaitForSingleObject(pi.hProcess, INFINITE)
