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.
