i386_get_ldt() will return the list of i386 descriptors
  that the process has in its LDT. i386_set_ldt() will
  set a list of i386 descriptors for the current process in its LDT. Both
  routines accept a starting selector number start_sel ,
  an array of memory that will contain the descriptors to be set or returned
  descs , and the number of entries to set or return
  num_sels.
The argument descs can be either
    segment_descriptor or gate_descriptor and are defined in
    <i386/segments.h> . These structures are
    defined by the architecture as disjoint bit-fields, so care must be taken in
    constructing them.
i386_get_ldt() returns the
  number of descriptors currently in the LDT.
  i386_set_ldt() returns the first selector set.
  Otherwise, a value of -1 is returned and the global variable
  errno is set to indicate the error.
i386_get_ldt() and
  i386_set_ldt() will fail if:
