<div class="sect1">
<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">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.</div>
<div class="paragraph">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.</div>
<div class="paragraph">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.</div>
<div class="paragraph">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.</div>
<div class="paragraph">The kbuffer_dup() function will duplicate an existing kbuffer structure with
an allocated new one. It will have all the properties of the passed in kbuf,
including pointing to the same subbuffer that was loaded in the kbuf.
It must be freed with kbuffer_free().</div>
<div class="paragraph">The kbuffer_free() function will free the resources created by kbuffer_alloc().</div>
<div class="paragraph">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.</div>
<div class="paragraph">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.</div>
<div class="paragraph">The kbuffer_refresh() is to be used if more writes were done on the loaded kbuffer
where the size of the kbuffer needs to be refreshed to be able to read the new
events that were written since the last kbuffer_load_subbuffer() was called on it.</div>
<div class="paragraph">Note, no memory barriers are implemented with this function and any synchronization
with the writer is the responsibility of the application.</div>
<div class="paragraph">The kbuffer_start_of_data() function returns the offset of where the actual
data load of the sub-buffer begins.</div>
<div class="paragraph">The kbuffer_subbuffer() function returns the pointer to the currently loaded
subbuffer. That is, the last subbuffer that was loaded by kbuffer_load_subbuffer().
If no subbuffer was loaded NULL is returned.</div>
</div>
</div>
<div class="sect1">
<h2 id="_return_value">RETURN VALUE</h2>
<div class="sectionbody">
<div class="paragraph">kbuffer_alloc() returns an allocated kbuffer descriptor or NULL on error.
The returned descriptor must be freed with kbuffer_free()</div>
<div class="paragraph">kbuffer_load_subbuffer() returns 0 on success and -1 on error.</div>
<div class="paragraph">kbuffer_subbuffer_size() returns the index on the subbuffer where the end
of the last event is located.</div>
<div class="paragraph">kbuffer_start_of_data() returns the offset of where the data begins on the
sub-buffer loaded in kbuf.</div>
<div class="paragraph">kbuffer_subbuffer() returns the last loaded subbuffer to kbuf that was loaded
by kbuffer_load_subbuffer() or NULL if none was loaded.</div>
<div class="paragraph">kbuffer_refresh() returns 0 on success and -1 if kbuf is NULL or it does not
have a subbuffer loaded via kbuffer_load_subbuffer().</div>
