SetThreadContext
The SetThreadContext function sets the context in the specified thread.
BOOL SetThreadContext(
HANDLE hThread,
| // handle of thread with context
| CONST CONTEXT *lpContext
| // address of context structure
| );
|
|
Parameters
hThread
Identifies an open handle of a thread whose context is to be written to.
Windows NT: The handle must have the THREAD_SET_CONTEXT access right to the thread. For
more information, see Thread Objects.
lpContext
Points to the address of a 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.
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
If the context was set, the return value is nonzero.
If the function fails, the return value is zero. 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.
