 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 routines for
a functional specification that clients of libthread_db and
librtld_db can use to implement this required interface. The
<proc_service.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.
