GetThreadSelectorEntry

The GetThreadSelectorEntry function retrieves a descriptor table entry for the specified selector and thread.

BOOL GetThreadSelectorEntry(

HANDLE hThread,	// handle of thread that contains selector
DWORD dwSelector,	// number of selector value to look up
LPLDT_ENTRY lpSelectorEntry	// address of selector entry structure
);

Parameters

hThread

Identifies a handle of the thread containing the specified selector.

Windows NT: The handle must have THREAD_QUERY_INFORMATION access. For more information, see Thread Objects.

dwSelector

Specifies the global or local selector value to look up in the thread's descriptor tables.

lpSelectorEntry

Points to a structure that receives a copy of the descriptor table entry if the specified selector has an entry in the specified thread's descriptor table. This information can be used to convert a segment-relative address to a linear virtual address.

Return Values

If the function succeeds, the return value is nonzero. In that case, the structure pointed to by the lpSelectorEntry parameter receives a copy of the specified descriptor table entry.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

GetThreadSelectorEntry is only functional on x86-based systems. For systems that are not x86-based, the function returns FALSE.

Debuggers use this function to convert segment-relative addresses to linear virtual addresses. The ReadProcessMemory and WriteProcessMemory functions use linear virtual addresses.
