.SH DESCRIPTION
.sp
.LP
Every program that links \fBlibthread_db\fR or \fBlibrtld_db\fR must provide a set of process control primitives that allow \fBlibthread_db\fR and \fBlibrtld_db\fR 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 \fBlibc_db\fR(3LIB). For information on \fBlibrtld_db\fR, refer to \fIRuntime Linker Debugger Interface\fR in \fIOracle Solaris 11.3 Linkers and Libraries         Guide\fR.
.sp
.LP
Refer to the individual reference manual pages that describe these routines for a functional specification that clients of \fBlibthread_db\fR and \fBlibrtld_db\fR can use to implement this required interface. The <\fBproc_service.h\fR> header lists the C declarations of these routines.
