> -DESCRIPTION
> ------------
> -These functions can be used to handle the mapping between pid and process name.
> -The library builds a cache of these mappings, which is used to display the name
> -of the process, instead of its pid. This information can be retrieved from
> -tracefs/saved_cmdlines file.
> -
> -The _tep_register_comm()_ function registers a _pid_ / process name mapping.
> -If a command with the same _pid_ is already registered, an error is returned.
> -The _pid_ argument is the process ID, the _comm_ argument is the process name,
> -_tep_ is the event context. The _comm_ is duplicated internally.
> -
> -The _tep_override_comm()_ function registers a _pid_ / process name mapping.
> -If a process with the same pid is already registered, the process name string is
> -udapted with the new one. The _pid_ argument is the process ID, the _comm_
> -argument is the process name, _tep_ is the event context. The _comm_ is
> -duplicated internally.
> -
> -The _tep_is_pid_registered()_ function checks if a pid has a process name
> -mapping registered. The _pid_ argument is the process ID, _tep_ is the event
> -context.
> -
> -The _tep_data_comm_from_pid()_ function returns the process name for a given
> -pid. The _pid_ argument is the process ID, _tep_ is the event context.
> -The returned string should not be freed, but will be freed when the _tep_
> -handler is closed.
> -
> -The _tep_data_pid_from_comm()_ function returns a pid for a given process name.
> -The _comm_ argument is the process name, _tep_ is the event context.
> -The argument _next_ is the cmdline structure to search for the next pid.
> -As there may be more than one pid for a given process, the result of this call
> -can be passed back into a recurring call in the _next_ parameter, to search for
> -the next pid. If _next_ is NULL, it will return the first pid associated with
> -the _comm_. The function performs a linear search, so it may be slow.
> -
> -The _tep_cmdline_pid()_ function returns the pid associated with a given
> -_cmdline_. The _tep_ argument is the event context.
> -
> -RETURN VALUE
> -------------
> -_tep_register_comm()_ function returns 0 on success. In case of an error -1 is

> ------------
> -
> -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.

> -DESCRIPTION
> ------------
> -The _tep_strerror()_ function converts tep error number into a human

> -The _tep_ argument is trace event parser context. The _errnum_ is a regular
> -errno, defined in errno.h, or a tep error number. The string, describing this
> -error number is copied in the _buf_ argument. The _buflen_ argument is
> -the size of the _buf_.
> -
> -It as a thread safe wrapper around strerror_r(). The library function has two
> -different behaviors - POSIX and GNU specific. The _tep_strerror()_ API always
> -behaves as the POSIX version - the error string is copied in the user supplied
> -buffer.
> -
> -RETURN VALUE
> -------------
> -The _tep_strerror()_ function returns 0, if a valid _errnum_ is passed and the
> -string is copied into _buf_. If _errnum_ is not a valid error number,
> --1 is returned and _buf_ is not modified.

> -DESCRIPTION
> ------------
> -The libtraceevent(3) library provides APIs to access kernel tracepoint events,
> -located in the tracefs file system under the events directory.
> -
> -ENVIRONMENT
> ------------
> -[verse]
> ---
> -TRACEEVENT_PLUGIN_DIR
> -	Additional plugin directory. All shared object files, located in this directory will be loaded as traceevent plugins.

> -FILES
> ------
> -[verse]
> ---
> -*event-parse.h*
> -	Header file to include in order to have access to the library APIs.
> -*trace-seq.h*
> -	Header file to include in order to have access to trace sequences related APIs.
> -	Trace sequences are used to allow a function to call several other functions
> -	to create a string of data to use.
> -*-ltraceevent*
> -	Linker switch to add when building a program that uses the library.
