libtracepoint-control-cpp

• perf-collect is a tool that collects tracepoint events into a perf.data file using the libtracepoint-control-cpp library. This tool is similar to the perf record command, but it includes special "pre-register" support to simplify collection of user_events tracepoints that are not yet registered when trace collection begins.
• TracepointSession.h implements an event collection session that can collect tracepoint events and enumerate the events that the session has collected.
• TracepointPath.h has functions for finding the /sys/kernel/tracing mount point and reading format files.
• TracepointName.h represents a tracepoint name (system name + event name); for instance, user_events:eventName.
• TracepointSpec.h represents a tracepoint specification (system name + event name + field definitions); for instance, user_events:eventName int field1.
• TracepointCache.h implements a cache for tracking parsed format files and locating cached data by TracepointName or by common_type id.
