Name

ps_lgetregs, ps_lsetregs, ps_lgetfpregs, ps_lsetfpregs, ps_lgetxregsize, 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);

Description

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.

SPARC Only

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.

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 architecture.

PS_ERR

The function did not return successfully.
