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
auxiliary vector of the target process.


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.

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.
