 161      -.LP
 162  158  Every program that links \fBlibthread_db\fR or \fBlibrtld_db\fR must provide a
 163  159  set of process control primitives that allow \fBlibthread_db\fR and
 164  160  \fBlibrtld_db\fR to access memory and registers in the target process, to start
 165  161  and to stop the target process, and to look up symbols in the target process.
 166  162  See \fBlibc_db\fR(3LIB). For information on \fBlibrtld_db\fR, refer to the
 167  163  \fILinker and Libraries Guide\fR.

 170  166  Refer to the individual reference manual pages that describe these routines for
 171  167  a functional specification that clients of \fBlibthread_db\fR and
