15 The reboot() function reboots the system. The howto argument specifies
16 the behavior of the system while rebooting and is a mask constructed by
17 a bitwise-inclusive-OR of flags from the following list:
18
19 RB_AUTOBOOT The machine is rebooted from the root filesystem on the
20 default boot device. This is the default behavior. See
21 boot(1M) and kernel(1M).
22
23
24 RB_HALT The processor is simply halted; no reboot takes place.
25 This option should be used with caution.
26
27
28 RB_ASKNAME Interpreted by the bootstrap program and kernel, causing
29 the user to be asked for pathnames during the bootstrap.
30
31
32 RB_DUMP The system is forced to panic immediately without any
33 further processing and a crash dump is written to the
34 dump device (see dumpadm(1M)) before rebooting.
35
36
37
38 Any other howto argument causes the kernel file to boot.
39
40
41 The interpretation of the bootargs argument is platform-dependent.
42
44 Upon successful completion, reboot() never returns. Otherwise, −1 is
45 returned and errno is set to indicate the error.
46
48 The reboot() function will fail if:
49
50 EPERM The {PRIV_SYS_CONFIG} privilege is not asserted in the effec‐
51 tive set of the calling process.
