# Functions
Parse parses, post-processes and verifies the trace.
Print dumps events to stdout.
PrintEvent dumps the event to stdout.

goroutine is unblocked [timestamp, goroutine id, seq, stack].
goroutine is unblocked on the same P as the last event [timestamp, goroutine id, stack].
denotes that goroutine is blocked when tracing starts [timestamp, goroutine id].
memstats.heap_live change [timestamp, heap_alloc].
memstats.next_gc change [timestamp, next_gc].
unused.
start of P [timestamp, thread id].
stop of P [timestamp].
stack [stack id, number of PCs, array of {PC, func string ID, file string ID, line}].
string dictionary entry [ID, length, string].
denotes timer goroutine [timer goroutine id].
Special P identifiers:.
depicts GC state.
depicts network unblocks.
depicts returns from syscalls.
depicts timer unblocks.
# Variables
BreakTimestampsForTesting causes the parser to randomly alter timestamps (for testing of broken cputicks).
ErrTimeOrder is returned by Parse when the trace contains time stamps that do not respect actual event ordering.
