Trace event parser context flags are defined in enum tep_flag:
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
Note: plugin related flags must me set before calling tep_load_plugins() API.
The tep_set_flag() function sets flag to tep context.
The tep_clear_flag() function clears flag from tep context.
The tep_test_flag() function tests if flag is set to tep context.
