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.

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.

ps_lgetLDT()

Reads the local descriptor table of the LWP.
