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 CONTEXTstructure that contains the context to be set in the specified thread.

The value of the ContextFlagsmember of this structure specifies which portions of a thread's context to set.

Some values in the CONTEXTstructure 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 ContextFlagsmember of the context structure.

The thread handle identified by the hThreadparameter is typically being debugged, but the function can also operate even when it is not.

Do not try to set the context for a running thread; the results are unpredictable.

To suspend the thread before calling SetThreadContext, use the SuspendThreadfunction.

Requirements

Header winbase.h
Library Nk.lib
Windows Embedded CE Windows CE 2.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
