ps_lgetregs(), ps_lsetregs(), ps_lgetfpregs(), ps_lsetfpregs(), ps_lgetxregsize(), ps_lgetxregs(), ps_lsetxregs() read and write register sets from lightweight processes (LWPs) within the target process identified by ph. ps_lgetregs() gets the general registers of the LWP identified by lid, and ps_lsetregs() sets them. ps_lgetfpregs() gets the LWP's floating point register set, while ps_lsetfpregs() sets it.

ps_lgetxregsize(),ps_lgetxregs(), andps_lsetxregs() are SPARC-specific. They do not need to be defined by a controlling process on non-SPARC architecture. ps_lgetxregsize() returns in *xregsize the size of the architecture-dependent extra state registers. ps_lgetxregs() gets the extra state registers, and ps_lsetxregs() sets them.
