.SH DESCRIPTION
.sp
.LP
\fBps_lgetregs()\fR, \fBps_lsetregs()\fR, \fBps_lgetfpregs()\fR, \fBps_lsetfpregs()\fR, \fBps_lgetxregsize()\fR, \fBps_lgetxregs()\fR, \fBps_lsetxregs()\fR, \fBps_lgetcxregsize()\fR, \fBps_lgetcxregs()\fR, and \fBps_lsetcxregs()\fR read and write register sets from lightweight processes (\fBLWP\fRs) within the target process identified by \fIph\fR. \fBps_lgetregs()\fR gets the general registers of the \fBLWP\fR identified by \fIlid\fR, and \fBps_lsetregs()\fR sets them. \fBps_lgetfpregs()\fR gets the \fBLWP\fR's floating point register set, while \fBps_lsetfpregs()\fR sets it.
.sp
.LP
\fBps_lgetxregsize()\fR, \fBps_lgetxregs()\fR, and \fBps_lsetxregs()\fR are system-dependent. \fBps_lgetxregsize()\fR returns in *\fIxregsize\fR the size of the architecture-dependent extra state registers.  \fBps_lgetxregs()\fR gets the extra state registers, and \fBps_lsetxregs()\fR sets them. On systems that do not support extra state registers, these functions will return \fBPS_NOXREGS\fR.
.sp
.LP
\fBps_lgetcxregsize()\fR, \fBps_lgetcxregs()\fR, and \fBps_lsetcxregs()\fR are system-dependent functions that handle CPU-specific extended registers. \fIps_lgetcxregsize\fR returns in *\fIcxregsize\fR the size of CPU-specific extended registers. \fBps_lgetxregs()\fR gets CPU extended registers, and \fBps_lsetxregs()\fR sets them. On systems that do not support extended registers, these functions will return \fBPS_NOCXREGS\fR.
