GetThreadSelectorEntry function (winbase.h)
Retrieves a descriptor table entry for the specified selector and thread.
Syntax
BOOL GetThreadSelectorEntry(
[in] HANDLE hThread,
[in] DWORD dwSelector,
[out] LPLDT_ENTRY lpSelectorEntry
);
Parameters
[in] hThread
A handle to the thread containing the specified selector. The handle must have THREAD_QUERY_INFORMATION access. For more information, see Thread Security and Access Rights.
[in] dwSelector
The global or local selector value to look up in the thread's descriptor tables.
[out] lpSelectorEntry
A pointer to an LDT_ENTRY 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 value
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.
