spltty(9)  modify system interrupt priority level

These functions raise and lower the system priority level. They are used by kernel code to block interrupts with priority less than or equal to the named level (i.e., spltty() blocks interrupts of pri... 
splvm(9)  modify system interrupt priority level

These functions raise and lower the system priority level. They are used by kernel code to block interrupts with priority less than or equal to the named level (i.e., spltty() blocks interrupts of pri... 
splx(9)  modify system interrupt priority level

These functions raise and lower the system priority level. They are used by kernel code to block interrupts with priority less than or equal to the named level (i.e., spltty() blocks interrupts of pri... 
srandom(9)  kernel library routines

The kern library implements a set of useful functions and macros inside the kernel. 
startuphook_disestablish(9)  add or remove a startup hook

The startuphook_establish() function adds fn to the list of hooks invoked by dostartuphooks(9) at startup. When invoked, the hook function fn will be passed arg as its only argument. The startuphook_d...

stathz(9)  system time model

The system is driven by hardclock(9) interrupts, which occur at hz frequency, and are used to keep track of real time. On systems where another independent clock is available, it is set at stathz freq...
