This is the syscall (kernel entry) that implements the write(2) kernel function. Then next function will be in kernel space, and will be the handler for SYS_write, the 'write' function in sys/kern/sys_generic.c. By "handles interrupts" I assume you meant the syscall interface, right? -- Where am I, and what am I doing in this handbasket?
