.SH DESCRIPTION
.sp
.LP
The \fBlibrtld_db\fR 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 \fBlibrtld_db\fR client that links with \fBlibrtld_db\fR and uses \fBlibrtld_db\fR to inspect or modify runtime linking aspects of one or more target processes. See the \fIRuntime Linker Debugger Interface\fR in \fIOracle Solaris 11.3 Linkers and Libraries         Guide\fR for a full description of the runtime linker debugger interface mechanism.
.SH USAGE
.sp
.LP
To use \fBlibrtld_db\fR, applications need to implement the interfaces documented in \fBps_pread\fR(3PROC) and \fBproc_service\fR(3PROC).
