Create a system call int sys_wolfie(void *buf, uint size), which copies an ASCII art image of Wolfie to a user-supplied buffer, provided that the buffer is large enough. You are welcome to use an ASCII art generator, or draw your own by hand. If the buffer is too small, or not valid, return a negative value. If the call succeeds, return the number of bytes copied.   B) Write a user-level application, called wolfietest.c, that gets the Wolfie image from the kernel, and prints it to the console. When the OS runs, your program's binary should be included in fs.img and listed if someone runs ls at the xv6 shell's command prompt.  Language in C

Question

a) Create a system call int sys_wolfie(void *buf, uint size), which copies an ASCII art image of Wolfie to a user-supplied buffer, provided that the buffer is large enough. You are welcome to use an ASCII art generator, or draw your own by hand.

If the buffer is too small, or not valid, return a negative value. If the call succeeds, return the number of bytes copied.

 

B) Write a user-level application, called wolfietest.c, that gets the Wolfie image from the kernel, and prints it to the console. When the OS runs, your program's binary should be included in fs.img and listed if someone runs ls at the xv6 shell's command prompt.
