CREATE_THREAD_DEBUG_INFO info  Overview  Group

The CREATE_THREAD_DEBUG_INFO structure contains thread-creation information that can be used by a debugger.

typedef struct _CREATE_THREAD_DEBUG_INFO { // ctdi 

    HANDLE hThread; 

    LPVOID lpThreadLocalBase; 

    LPTHREAD_START_ROUTINE lpStartAddress; 

} CREATE_THREAD_DEBUG_INFO; 

 

Members

hThread

Identifies a handle of the thread whose creation caused the debugging event. If this member is NULL, the handle is not valid. Otherwise, the debugger has THREAD_GET_CONTEXT, THREAD_SET_CONTEXT, and THREAD_SUSPEND_RESUME access to the thread, allowing the debugger to read from and write to the registers of the thread and control execution of the thread.

lpThreadLocalBase

Points to a block of data. At offset 0x2C into this block is another pointer, called ThreadLocalStoragePointer, that points to an array of per-module thread local storage blocks. This gives a debugger access to per-thread data in the threads of the process being debugged using the same algorithms that a compiler would use.

lpStartAddress

Points to the starting address of the thread. This value may only be an approximation of the thread’s starting address, because any application with appropriate access to the thread can change the thread’s context by using the SetThreadContext function.
