The attribute is constructor, so the function will be directly called before the execution of main. I think that for your case, you just need to change the configuration file.

Thanks for the update.
I am still not clear who should call the function SPDK_SUBSYSTEM_REGISTER. I just wanted to add virtual mode subsystem as the NVMe/F target. In configuration the Virtual has two Malloc drives. So even before the main function I should create these devices and add. I find SPDK_SUBSYSTEM_REGISTER in lib/bdev/malloc/blocdev_malloc.c . So who should call this function? Should I call it by writing a separate program.
Thanking You,
