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.
FUNCTIONSps_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.
