Use getentropy() to get seed material when using glibc >= 2.25
getentropy() uses the getrandom syscall on Linux to avoid file descriptors.
It is never interputed (EINTR) and uses the same source as /dev/urandom.
https://man7.org/linux/man-pages/man3/getentropy.3.html
getrandom has been in the Linux since kernel 3.17
When unavailable (ENOSYS), fallback to /dev/urandom.

defaulting the copy constructor. This is needed because the assignment
operator is deleted.
