SetThreadContext (Compact 2013)

3/28/2014

This function sets the context in the specified thread.

Syntax

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

Parameters

• hThread
  [in] Handle to the thread that contains the context to be set.

• lpContext
  [in] 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 thread's context to set.

  Some values in the CONTEXT structure that cannot be specified are silently set to the correct value, including the following:

  • Bits in the CPU status register that specify the privileged processor mode
  • Global enabling bits in the debugging register
  • Other states that must be controlled by the OS

Return Value

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.

SetThreadContext can be called by processes with SYSTEM_TOKEN.

The thread handle identified by the hThread parameter is typically being debugged. Do not try to set the context for a running thread; the results are unpredictable.

To suspend the thread before calling SetThreadContext, use the SuspendThread function.
