+--
+
+DESCRIPTION
+-----------
+These functions create a _kbuffer_ handle that can be used to parse the raw sub buffers
+of the Linux kernel tracing ring buffer. The ring buffer is found in the tracefs
+directory, and can be retrieved by *tracefs_instance_get_file(3)* at
+*per_cpu/cpuX/trace_pipe_raw* where *X* is replaced by the per CPU number of
+the specified ring buffer. The ring buffer inside the kernel is split up per
+CPU, such that the raw ring buffer must be retrieved per CPU as well.
+
+The *kbuffer_alloc()* will create a descriptor that can be used to manage a sub buffer
+read by the ring buffer. The _size_ parameter denotes what the word size is
+for the given buffer (note, this works from reading raw data from machines other
+than the machine that is calling this function). The _endian_ denotes the endian
+for the machine.
+
+If _endian_ is set to _KBUFFER_ENDIAN_SAME_AS_HOST_ the endian will be set to the same
+as the host endianess, which is useful when the application is reading the
+ring buffer data directly from the same machine it is running on.
+
+If _size_ is set to _KBUFFER_LSIZE_SAME_AS_HOST_, if the word size is 8, it will
+set the kbuffer descriptor to long size of 8. But if the size is 4, then it
+will then perform a *uname(2)* call, and if the _machine_ field has the string "64"
+in it, it will be set to 8 byte long size and not 4 byte. This is because the
+ring buffer long size is dependent on the kernel and not user space.
+
+The *kbuffer_free()* function will free the resources created by *kbuffer_alloc()*.
+
+The *kbuffer_load_subbuffer()* will take a _subbuffer_ which is a raw data blob
+from the tracefs *trace_pipe_raw* file. The Linux tracing ring buffer is broken up
+into sub buffers. Each sub buffer is as stand alone data segment that has all the
+information to split out the individual events and time stamps. This sub buffer
+is what kbuffer uses to walk the events.
+
+The *kbuffer_subbuffer_size()* returns the location of the end of the last event
+on the sub-buffer. It does not return the size of the sub-buffer itself.
+
+The *kbuffer_start_of_data()* function returns the offset of where the actual
+data load of the sub-buffer begins.
+
+RETURN VALUE
+------------
+*kbuffer_alloc()* returns an allocated kbuffer descriptor or NULL on error.
+The returned descriptor must be freed with *kbuffer_free()*
+
+*kbuffer_load_subbuffer()* returns 0 on success and -1 on error.
+
+*kbuffer_subbuffer_size()* returns the index on the subbuffer where the end
+of the last event is located.
+
+*kbuffer_start_of_data()* returns the offset of where the data begins on the
+sub-buffer loaded in _kbuf_.

+kbuffer_read_event, kbuffer_next_event, kbuffer_missed_events, kbuffer_event_size, kbuffer_curr_size,
+kbuffer_curr_offset, kbuffer_curr_index -
+Functions to read through the kbuffer sub buffer.
+
+SYNOPSIS
+--------
+[verse]
+--
+*#include <kbuffer.h>*
+
+void pass:[*]*kbuffer_read_event*(struct kbuffer pass:[*]_kbuf_, unsigned long long pass:[*]_ts_);
+void pass:[*]*kbuffer_next_event*(struct kbuffer pass:[*]_kbuf_, unsigned long long pass:[*]_ts_);

+int *kbuffer_curr_offset*(struct kbuffer pass:[*]_kbuf_);
+int *kbuffer_curr_index*(struct kbuffer pass:[*]_kbuf_);
+--
+
+DESCRIPTION
+-----------
+The function *kbuffer_read_event()* reads the next event in the _kbuf_ descriptor
+and if _ts_ is non NULL, will place its timestamp into it. This does not modify the _kbuf_
+descriptor, and calling this function mulitple times will return the same result.
+
+The function *kbuffer_next_event()* will return the next event in the _kbuf_ descriptor.
+It will also set the _ts_ to the timestamp of the returned event. NULL is returned
+if there are no more events and _ts_ will be undefined. Note, if this is called directly
+after a *kbuffer_load_subbuffer()* then it will likely give an unexpected result, as it
+will return the second event and not the first event. Usually this function is only used
+to move to the next event and to know if there's any more events to read, and
+*kbuffer_read_event()* is always called first.
+
+The function *kbuffer_read_at_offset()* returns the event located at a given _offset_ from
+the beginning of the sub-buffer. This offset can be retrieved by *kbuffer_curr_offset()*.
+If _ts_ points to an unsigned long long, then it will be set to the event at the given
+offset's timestamp.
+
+If the sub-buffer had missed events before it, then *kbuffer_missed_events()* will return
+the non zero. If it returns -1, that means there were missed events, but the exact number
+of missed events is unknown. If it returns a positive number, then the number of missed events
+is the return value.
+
+The *kbuffer_event_size()* function returns the size of the data portion of the current event
+(the one that would be returned by *kbuffer_read_event()*.
+
+The *kbuffer_curr_size()* function returns the entire record size of the current event
+(the one that would be returned by *kbuffer_read_event()*. The difference here is that the
+return value includes the size of the event record meta data that is not part of what
+is returned by *kbuffer_read_event()*.
+
+The *kbuffer_curr_offset()* function returns the offset from the beginning of the sub-buffer
+of where the current event's meta data for the record begins. The first event will
+not be at offset zero. This offset can be used to retrieve the event with
+*kbuffer_read_at_offset()*.
+
+The *kbuffer_curr_index()* function returns the index from the beginning of the data
+portion of the sub-buffer where the current evnet's meta data is located.
+The first event will likely be zero, but may not be if there's a timestamp attached to it.
+
+RETURN VALUE
+------------
+*kbuffer_read_event()* returns the event that the _kbuf_ descriptor is currently at,
+or NULL if the last event was passed (by *kbuffer_next_event()*).
+
+*kbuffer_next_event()* returns the next event after the current event or NULL if there
+are no more events.
+
+*kbuffer_read_at_offset()* returns the event at a given _offset_ from the start of
+the sub-buffer stored in _kbuf_, or NULL if there exists no event. Note, _offset_
+only needs to be an offset that lands on the record, or is at the start of it. It does
+not need to be exactly at the beginning of the record.
+
+*kbuffer_missed_events()* returns 0 if there were no missed events before loaded sub-buffer.
+Returns -1 if there were an unknown number of missed events, or if the number of missed events
+is known, that number will be returned.
+
+*kbuffer_event_size()* returns the size of the data payload of the current event of _kbuf_.
+
+*kbuffer_curr_size()* returns the size of the entire record of the current event of _kbuf_.
+This includes the size of the meta data for that record.
+
+*kbuf_curr_offset()* returns the offset of the current record from the beginning of the _kbuf_
+sub-buffer.
+
+*kbuf_curr_index()* returns the index of the current record from the beginning of the _kbuf_
+data section.
