NAME

       libdtrace - DTrace dynamic tracing software library

DESCRIPTION

       Functions  in this library define the interface for interacting with the DTrace dynamic tracing software, including the D language compiler
       and facilities for enabling probes and consuming trace data.

INTERFACES

       The interfaces provided by libdtrace.so.1 are currently private to the implementation of the Solaris system and DTrace  subsystem  and  are
       subject	to  change  at	any  time  without notice.  Applications using these interfaces might fail to run on future releases. Refer to the
       Solaris Dynamic Tracing Guide for a description of the public documented interfaces available for the DTrace facility.
