+.Os FreeBSD
+.Sh NAME
+.Nm i386_get_ldt ,
+.Nm i386_set_ldt
+.Nd manage i386 per-process Local Descriptor Table entries
+.Sh SYNOPSIS
+.Fd #include <machine/segments.h>
+.Fd #include <machine/sysarch.h>
+.Ft int
+.Fn i386_get_ldt "int start_sel" "union descriptor *descs" "int num_sels"
+.Ft int
+.Fn i386_set_ldt "int start_sel" "union descriptor *descs" "int num_sels"
+.Sh DESCRIPTION
+.Fn i386_get_ldt
+will return the list of i386 descriptors that the process has in its
+LDT.
+.Fn i386_set_ldt
+will set a list of i386 descriptors for the current process in its
+LDT.
+Both routines accept a starting selector number
+.Fa start_sel
+, an array of memory that
+will contain the descriptors to be set or returned
+.Fa descs
+, and the number of entries to set or return
+.Fa num_sels .
+.Pp
+The argument
+.Fa descs
+can be either segment_descriptor or gate_descriptor and are defined in
+.Fd <i386/segments.h> .
+These structures are defined by the architecure
+as disjoint bit-fields, so care must be taken in constructing them.
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn i386_get_ldt
+returns the number of descriptors currently in the LDT.
+.Fn i386_set_ldt
+returns the first selector set.
+Otherwise, a value of -1 is returned and the global
+variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Fn i386_get_ldt
+and
+.Fn i386_set_ldt
+will fail if:
+.Bl -tag -width [EINVAL]
+.It Bq Er EINVAL
+An inappropriate parameter was used for
+.Fa start_sel
+or
+.Fa num_sels .
+.It Bq Er EACESS
+The caller attempted to use a descriptor that would
+circumvent protection or cause a failure.
