[netCDF #NXI-317344]: Question about nc_create

Hello Stefano,

NetCDF does not support single-writer/multi-reader in many cases. It is 
possible to use `nc_open_mem` and `nc_open_memio` to access data stored in 
memory, which may be an option for you.  You can also use `nc_sync()` to 
synchronize a dataset to disk, although you will need to coordinate the timing 
of this between your programs. 

I hope this helps,

-Ward
