Can I call dr_app_setup_and_start in a signal handler ?

[吕志宏]

I want to perform tracing at a certain stage during application execution. Is it possible to call `dr_app_setup_and_start` by sending a signal? Or is there a better alternative?

Could you modify the application?

> If the application can be modified, it can be linked with the \p drmemtrace
tracer and use DynamoRIO's start/stop API routines dr_app_setup_and_start()
and dr_app_stop_and_cleanup() to delimit the desired trace region.

Please see https://github.com/DynamoRIO/dynamorio/blob/master/suite/tests/api/static_sideline.c

for an example.
