Attach a callback to a range of events
#include <sys/traceparser.h> int traceparser_cs_range ( struct traceparser_state * stateptr, void * userdata, tracep_callb_func_t funcptr, unsigned class, unsigned firstevent, unsigned lastevent );
libtraceparser
Use the -l traceparser option to qcc to link against this library.
The traceparser_cs_range() function attaches a callback function, given by the pointer funcptr, to a range of events from firstevent through to lastevent inclusive, from one particular class. You'll use this function if you're creating your own utility for parsing trace data (as an alternative to traceprinter).
The user data (userdata) is passed to the registered callback function (funcptr) upon execution. The stateptr is an opaque structure obtained from traceparser_init().
