#include <event-parse.h>

        TEP_NSEC_OUTPUT,


        TEP_DISABLE_SYS_PLUGINS,

TEP_NSEC_OUTPUT - print event’s timestamp in nano seconds, instead of micro seconds.
TEP_DISABLE_SYS_PLUGINS - disable plugins, located in system’s plugin


                        directory. This directory is defined at library compile


                        time, and usually depends on library installation


                        prefix: (install_preffix)/lib/traceevent/plugins
TEP_DISABLE_PLUGINS - disable all library plugins:


                        - in system’s plugin directory


                        - in directory, defined by the environment variable TRACEEVENT_PLUGIN_DIR


                        - in user’s home directory, ~/.traceevent/plugins
