Module Summary

Interface to dynamic tracing

Description

This module implements interfaces to dynamic tracing, should such be compiled into the virtual machine. For a standard and/or commercial build, no dynamic tracing is available, in which case none of the functions in this module is usable or give any effect.

Should dynamic tracing be enabled in the current build, either by configuring with ./configure --with-dynamic-trace=dtrace or with ./configure --with-dynamic-trace=systemtap, the module can be used for two things:

• Trigger the user-probe user_trace_i4s4 in the NIF library dyntrace.so by calling dyntrace:p/{1,2,3,4,5,6,7,8}.
