Hellо.c is а user prоgrаm sоurce thаt makes a system call getHello to print “Hello COP4610” when it executes in xv6 OS. You need to implement a system call handler sys_getHello(void) that fills the char array name[ ] in its user address space with "Hello COP4610" . Write sys_getHello(void) below. Hello.c: int main() { char name[512]; if (getHello(name) < 0) printf(1, "sys call getHello failsn"); printf(1, "%sn", name); exit();} sysproc.c: int sys_getHello(void) { char *s; // add your code below // don't change the code below return 0;}
