class ProcessProxy

Defined at line 38 of file ../../src/sys/fuzzing/realmfuzzer/engine/process-proxy.h

This class presents an interface to the engine for a instrumented target process. It tracks the

LLVM modules associated with the process and synchronizes coverage collection with fuzzing runs.

It also monitors the process for crashes and abnormal exits.

zx_status_t Finish ()

Signals the associated process that a fuzzing run is finishing.

Defined at line 124 of file ../../src/sys/fuzzing/realmfuzzer/engine/process-proxy.cc

Promise<bool, uint64_t> AwaitFinish ()

Returns a promise that completes either when the process acknowledges a (possibly subsequent)

call to |Finish|, or when it encounters an error. The promise returns whether any memory leaks

are suspected when successful, and the proxy's target ID on error.

zx_status_t GetStats (ProcessStats * out)

////////////////////////////////////////////////////////////

Status-related methods.

Defined at line 142 of file ../../src/sys/fuzzing/realmfuzzer/engine/process-proxy.cc

ZxPromise<FuzzResult> GetResult ()

Promises to return the fuzzing result from a process that encountered a fatal error. Waits for

the process to terminate.

Defined at line 144 of file ../../src/sys/fuzzing/realmfuzzer/engine/process-proxy.cc

size_t Dump (void * buffer, size_t size)

Dumps information about all threads in a process to the provided buffer. Returns the number of

bytes written, not including the null-terminator.
