This function retrieves the context of the specified thread.

At a Glance

Header file: Winbase.h
Windows CE versions: 2.0 and later

Syntax

BOOL GetThreadContext( HANDLE hThread, LPCONTEXT lpContext);

Parameters

hThread

Handle to the thread whose context is to be retrieved.

lpContext

Pointer to the CONTEXT structure that receives the appropriate context of the specified thread. The value of the ContextFlags member of this structure specifies which portions of a thread’s context are retrieved. The CONTEXT structure is highly computer specific. Currently, there are CONTEXT structures defined for Intel, MIPS, Alpha, ARM, SHx, and PowerPC processors. Refer to the header file WINNT.H for definitions of these structures.

Return Values

Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.

Remarks

The GetThreadContext function is used to retrieve the context of the specified thread. The function allows a selective context to be retrieved 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 when it is not being debugged.

You cannot get a valid context for a running thread. Use the SuspendThread function to suspend the thread before calling GetThreadContext.
