lwpid_t lid, prgregset_t gregset)

ps_err_e ps_lsetregs(const struct ps_prochandle ∗ph,

ps_err_e ps_lsetfpregs(const struct ps_prochandle ∗ph,

lwpid_t lid, prgregset_t gregset)

ps_err_e ps_lgetxregsize(const struct ps_prochandle ∗ph,

lwpid_t lid, int ∗xregsize)

ps_err_e ps_lgetxregs(const struct ps_prochandle ∗ph,

DESCRIPTION

ps_lgetregs, ps_lsetregs, ps_lgetfpregs, ps_lsetfpregs, ps_lgetxregsize, ps_lgetxregs , ps_lsetxregs read and write register sets from lightweight processes ( LWP ´s) 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_getxregsize, ps_getxregs, and ps_setxregs are SPARC-specific. They do not need to be defined by a controlling process on non-SPARC architecture.  ps_getxregsize returns in ∗xregsize the size of the architecture-dependent extra state registers.  ps_getxregs gets the extra state registers, and ps_setxregs 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.
