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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
