DESCRIPTION
       Every  program that links libthread_db or librtld_db must provide a set
       of process control primitives that allow libthread_db and librtld_db to
       access memory and registers in the target process, to start and to stop
       the target process, and to look up symbols in the target process.   See
       libc_db(3LIB).  For  information on librtld_db, refer to the Linker and
       Libraries Guide.

       Refer to the individual reference manual pages that describe these rou‐
       tines  for  a functional specification that clients of libthread_db and
       librtld_db can use to implement this required interface. The <proc_ser‐
       vice.h> header lists the C declarations of these routines.

FUNCTIONS
       ps_pdmodel()
			      Returns the data model of the target process.

       ps_pglobal_lookup()
			      Looks  up	 the symbol in the symbol table of the
			      load object in the target	 process  and  returns
			      its address.

       ps_pglobal_sym()
			      Looks  up	 the symbol in the symbol table of the
			      load object in the target	 process  and  returns
			      its symbol table entry.

       ps_pread()
			      Copies size bytes from the target process to the
			      controlling process.

       ps_pwrite()
			      Copies size bytes from the  controlling  process
			      to the target process.

       ps_pdread()
			      Identical to ps_pread().

       ps_pdwrite()
			      Identical to ps_pwrite().

       ps_ptread()
			      Identical to ps_pread().

       ps_ptwrite()
			      Identical to ps_pwrite().

       ps_pstop()
			      Stops the target process.

       ps_pcontinue()
			      Resumes target process.

       ps_lstop()
			      Stops  a	single	lightweight  process  (	 LWP )
			      within the target process.

       ps_lcontinue()
			      Resumes a single LWP within the target process.

       ps_lgetregs()
			      Gets the general registers of the LWP.

       ps_lsetregs()
			      Sets the general registers of the LWP.

       ps_lgetfpregs()
			      Gets the LWP`s floating point register set.

       ps_lsetfpregs()
			      Sets the LWP`s floating point register set.

       ps_pauxv()
			      Returns a pointer to a  read-only	 copy  of  the
			      target process's auxiliary vector.

       ps_kill()
			      Sends signal to target process.

       ps_lrolltoaddr()
			      Rolls the LWP out of a critical section when the
			      process is stopped.

       ps_plog()
			      Logs a message.

   SPARC
       ps_lgetxregsize()
			    Returns the	 size  of  the	architecture-dependent
			    extra state registers.

       ps_lgetxregs()
			    Gets the extra state registers of the LWP.

       ps_lsetxregs()
			    Sets the extra state registers of the LWP.

   x86
       ps_lgetLDT()
		       Reads the local descriptor table of the LWP.
