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.

To use librtld_db, applications need to implement the interfaces documented in ps_pread(3PROC) and proc_service(3PROC).
