[in] The operating system identifier of a thread in the target process.
[in] The size of the context.
[in] Pointer to a buffer containing the context.
The data in the context buffer will be in the format of the Win32 CONTEXT structure. The context specifies processor-specific register data, so the definition of the Win32 CONTEXT structure depends on the processor's architecture. Refer to the WinNT.h header file for the definition of the Win32 CONTEXT structure.
