So that we can specify a FILE object where to direct the formatted output.

2014-01-15tools lib traceevent: Check return value of realloc()Namhyung Kim1-4/+9
If realloc() fails, it'll leak the buffer. Also increate buffer size only if the allocation succeeded.

2014-01-15tools lib traceevent: Add state member to struct trace_seqNamhyung Kim1-13/+42
The trace_seq->state is for tracking errors during the use of trace_seq APIs and getting rid of die() in it.

2013-07-12tools lib traceevent: Add trace_seq_reset()Namhyung Kim1-0/+13
Sometimes it'd be useful if existing trace_seq can be reused. But currently it's impossible since there's no API to reset the trace_seq. Let's add trace_seq_reset() for this case.

2012-04-25events: Update tools/lib/traceevent to work with perfSteven Rostedt1-0/+1
Some of the util functions of libtraceevent.a conflict with perf, such as die(), warning() and others. Move them into event-util.h that is not included by the perf tools. Also, as perf compiles with 'bool' the filter_arg->bool needs to be renamed to filter_arg->boolean.

2012-04-25tools/events: Add files to create libtraceevent.aSteven Rostedt1-0/+199
Copy over the files from trace-cmd to the Linux tools directory such that applications like perf and latencytrace can use the more advanced parsing code. Because some of the file names of perf conflict with trace-cmd file names, the trace-cmd files have been renamed as follows: parse-events.c ==> event-parse.c parse-events.h ==> event-parse.h utils.h ==> event-utils.h The files have been updated to handle the changes to the header files but other than that, they are identical to what was in the trace-cmd repository. The history of these files, including authorship is available at the git repo: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git The Makefile was also copied over, but most of it was removed to focus on the parse-events code first. The parts of the Makefile for the plugins have also been removed, but will be added back when the plugin code is copied over as well. But that may be in its own separate directory.
