DESCRIPTION
The librtld_db library provides support for monitoring and manipulating
runtime linking aspects of a program. There are at least two processes
involved, the controlling process and one or more target processes.
The controlling process is the librtld_db client that links with
librtld_db and uses librtld_db to inspect or modify runtime linking
aspects of one or more target processes. See the Linker and Libraries
Guide for a full description of the runtime linker debugger interface
mechanism.
USAGE
To use librtld_db, applications need to implement the interfaces docu‐
mented in ps_pread(3PROC) and proc_service(3PROC).
