+tep_print_event - Writes event information into a trace sequence.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+*#include <trace-seq.h>*
+
+void *tep_print_event*(struct tep_handle pass:[*]_tep_, struct trace_seqpass:[*]_s_, struct tep_record pass:[*]_record_, const char pass:[*]_fmt_, _..._)
+--
+
+DESCRIPTION
+-----------
+
+The _tep_print_event()_ function parses the event information of the given
+_record_ and writes it into the trace sequence _s_, according to the format
+string _fmt_. The desired information is specified after the format string.
+The _fmt_ is printf-like format string, following arguments are supported:
+[verse]
+--
+ TEP_PRINT_PID, "%d" - PID of the event.
+ TEP_PRINT_CPU, "%d" - Event CPU.
+ TEP_PRINT_COMM, "%s" - Event command string.
+ TEP_PRINT_NAME, "%s" - Event name.
+ TEP_PRINT_LATENCY, "%s" - Latency of the event. It prints 4 or more
+ fields - interrupt state, scheduling state,
+ current context, and preemption count.
+ Field 1 is the interrupt enabled state:
+ d : Interrupts are disabled
+ . : Interrupts are enabled
+ X : The architecture does not support this
+ information
+ Field 2 is the "need resched" state.
+ N : The task is set to call the scheduler when
+ possible, as another higher priority task
+ may need to be scheduled in.
+ . : The task is not set to call the scheduler.
+ Field 3 is the context state.
+ . : Normal context
+ s : Soft interrupt context
+ h : Hard interrupt context
+ H : Hard interrupt context which triggered
+ during soft interrupt context.
+ z : NMI context
+ Z : NMI context which triggered during hard
+ interrupt context
+ Field 4 is the preemption count.
+ . : The preempt count is zero.
+ On preemptible kernels (where the task can be scheduled
+ out in arbitrary locations while in kernel context), the
+ preempt count, when non zero, will prevent the kernel
+ from scheduling out the current task. The preempt count
+ number is displayed when it is not zero.
+ Depending on the kernel, it may show other fields
+ (lock depth, or migration disabled, which are unique to
+ specialized kernels).
+ TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be
+ specified as part of this format string:
+ "%precision.divisord". Example:
+ "%3.1000d" - divide the time by 1000 and print the first
+ 3 digits before the dot. Thus, the time stamp
+ "123456000" will be printed as "123.456"
+ TEP_PRINT_INFO, "%s" - event information.
+ TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

+NAME
+----
+tep_load_plugins, tep_unload_plugins - Load / unload traceevent plugins.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <event-parse.h>*
+
+struct tep_plugin_list pass:[*]*tep_load_plugins*(struct tep_handle pass:[*]_tep_);
+void *tep_unload_plugins*(struct tep_plugin_list pass:[*]_plugin_list_, struct tep_handle pass:[*]_tep_);
+--
+
+DESCRIPTION
+-----------
+The _tep_load_plugins()_ function loads all plugins, located in the plugin
+directories. The _tep_ argument is trace event parser context.
+The plugin directories are :
+[verse]
+--
+ - System's plugin directory, defined at the library compile time. It
+ depends on the library installation prefix and usually is
+ _(install_preffix)/lib/traceevent/plugins_
+ - Directory, defined by the environment variable _TRACEEVENT_PLUGIN_DIR_
+ - User's plugin directory, located at _~/.local/lib/traceevent/plugins_
+--
+Loading of plugins can be controlled by the _tep_flags_, using the
+_tep_set_flag()_ API:
+[verse]
+--
+ _TEP_DISABLE_SYS_PLUGINS_ - do not load plugins, located in
+ the system's plugin directory.
+ _TEP_DISABLE_PLUGINS_ - do not load any plugins.
+--
+The _tep_set_flag()_ API needs to be called before _tep_load_plugins()_, if
+loading of all plugins is not the desired case.
+
+The _tep_unload_plugins()_ function unloads the plugins, previously loaded by
+_tep_load_plugins()_. The _tep_ argument is trace event parser context. The
+_plugin_list_ is the list of loaded plugins, returned by
+the _tep_load_plugins()_ function.
+
+RETURN VALUE
+------------
+The _tep_load_plugins()_ function returns a list of successfully loaded plugins,
+or NULL in case no plugins are loaded.
+
+EXAMPLE
+-------
+[source,c]
+--
+#include <event-parse.h>
+...
+struct tep_handle *tep = tep_alloc();
+...
+struct tep_plugin_list *plugins = tep_load_plugins(tep);
+if (plugins == NULL) {
+ /* no plugins are loaded */
+}
+...
