Librarize perf record, then in your code do something like:

#include "perf_record.h"

handle = perf_record_init(); /* creates perf events and creates
a record thread that writes samples
to perf.data, consumes env(PERF_*)
for configuration, registers with
at_exit() for cleanup */
if (!handle)
/* burn */

/* do you other code */

perf_record_start(handle);

/* do the bit you want profiled */

perf_record_stop(handle);

Then build with -lperfrecord or so. Not too hard, right?
