Is it possible to create files in SimGrid?
For example, after some execution program creates file and writes output onto it with Msg_file_write().
For this purpose I tried to use Msg_file_open() with nonexistent name expecting that simgrid would create a new file. But compiler only gave me an
Segmentation fault.
The behavior of MSG_file_write and MSG_file_open is exemplified in https://github.com/simgrid/simgrid/blob/master/examples/msg/io-file/io-file.c and https://github.com/simgrid/simgrid/blob/master/examples/msg/io-storage/io-storage.c
About your specific issue, more than "I got a Segmentation fault" is needed to help you. Do you have any minimal working example that reproduces your issue, or at least some backtrace?
