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.
