ps_lgetregs(3PROC) Process Control Library Functions ps_lgetregs(3PROC)NAME
ps_lgetregs, ps_lsetregs, ps_lgetfpregs, ps_lsetfpregs, ps_lgetxreg‐
size, ps_lgetxregs, ps_lsetxregs - routines that access the target
process register in libthread_db
SYNOPSIS
#include <proc_service.h>
ps_err_e ps_lgetregs(struct ps_prochandle *ph, lwpid_t lid,
prgregset_t gregset);
ps_err_e ps_lsetregs(struct ps_prochandle *ph, lwpid_t lid,
static prgregset_t gregset);
ps_err_e ps_lgetfpregs(struct ps_prochandle *ph, lwpid_t lid,
prfpregset_t *fpregs);
ps_err_e ps_lsetfpregs(struct ps_prochandle *ph, lwpid_t lid,
static prfpregset_t *fpregs);
ps_err_e ps_lgetxregsize(struct ps_prochandle *ph, lwpid_t lid,
int *xregsize);
ps_err_e ps_lgetxregs(struct ps_prochandle *ph, lwpid_t lid,
caddr_t xregset);
ps_err_e ps_lsetxregs(struct ps_prochandle *ph, lwpid_t lid,
caddr_t xregset);
DESCRIPTIONps_lgetregs(), ps_lsetregs(), ps_lgetfpregs(), ps_lsetfpregs(),
ps_lgetxregsize(), ps_lgetxregs(), ps_lsetxregs() read and write regis‐
ter 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(), and ps_lsetxregs() are system depen‐
dent. ps_lgetxregsize() returns in *xregsize the size of the architec‐
ture-dependent extra state registers. ps_lgetxregs() gets the extra
state registers, and ps_lsetxregs() sets them. On systems that do not
support extra state registers, these functions will return PS_NOXREGS.
RETURN VALUES
PS_OK The call returned successfully.
PS_NOFPREGS Floating point registers are neither available for this
architecture nor for this process.
PS_NOXREGS Extra state registers are not available on this system.
PS_ERR The function did not return successfully.
