SetThreadContext

This function sets the context in the specified thread.

BOOL SetThreadContext( 
HANDLE hThread, 
CONST CONTEXT * lpContext );

Parameters

• hThread
  Handle to the thread whose context is to be set.
• lpContext
  Pointer to the CONTEXT structure that contains the context to be set in the specified thread. The value of the ContextFlags member of this structure specifies which portions of a threads context to set. Some values in the CONTEXT structure that cannot be specified are silently set to the correct value. This includes bits in the CPU status register that specify the privileged processor mode, global enabling bits in the debugging register, and other states that must be controlled by the operating system.

Return Values

Nonzero indicates that the context was set. Zero indicates failure. To get extended error information, call GetLastError.

Remarks

The function allows the selective context to be set based on the value of the ContextFlags member of the context structure. The thread handle identified by the hThread parameter is typically being debugged, but the function can also operate even when it is not being debugged.

Do not try to set the context for a running thread; the results are unpredictable. Use the SuspendThread function to suspend the thread before calling SetThreadContext.

Requirements
