  39   39  DESCRIPTION
  40   40         ps_lgetregs(), ps_lsetregs(), ps_lgetfpregs(), ps_lsetfpregs(),
  41   41         ps_lgetxregsize(), ps_lgetxregs(), ps_lsetxregs() read and write
  42   42         register sets from lightweight processes (LWPs) within the target
  43   43         process identified by ph.  ps_lgetregs() gets the general registers of
  44   44         the LWP identified by lid, and ps_lsetregs() sets them. ps_lgetfpregs()
  45   45         gets the LWP's floating point register set, while ps_lsetfpregs() sets
  46   46         it.
  47   47  
  48   48         ps_lgetxregsize(), ps_lgetxregs(), and ps_lsetxregs() are used to get
  49   49         and set the extended register set. Support for an extended register set
  50   50         depends on the instruction-set archicture. On platforms without support
  51   51         for these, controlling processes wlil still need to define them;
  52   52         however, they are allowed to simply return errors.
  53   53  
  54   54         ps_lgetxregsize() returns in *xregsize the size of the architecture-
  55   55         dependent extra state registers. ps_lgetxregs() gets the extra state
  56   56         registers, and ps_lsetxregs() sets them. When getting the registers,
  57   57         the size of xregset must be at least the size returned by
  58   58         ps_lgetxregsize().

  60   60  RETURN VALUES
  61   61         PS_OK
