Hello,
Processes can change their Local Descriptor Table using
modify_ldt() system called.
see "man  modify_ldt" or :
(for x386 look at include/asm-i386/unistd.h:
#define __NR_modify_ldt         123)

However, usually there is no need to manipulate the LDT
with this system call.

I saw in wine a call to modify_ldt()  (libs/wine/ldt.c)

I was wondering in which occasions is this
system call being invoked: did anybody had encountered (or used himeslf)
a call to modify_ldt() in other apps (emulators maybe ? ).
