hello , iam trying to port code from openssl , especially at this time i need the function Rand_poll() https://github.com/openssl/openssl/blob/master/crypto/rand/rand_unix.c lines 237 - 420
The function Rand_poll use 1)getpid() 2)close(..) 3)open(...) 4getuid() and all this functions are defined on unistd.h ! any idea someone how i can run this code on kernel level?
