  1. Spl

    spl is the name for a collection of Unix interrupt priority control functions. SPL is short for "Set Priority Level". The functions include splhigh, splserial, splsched, splclock, splstatclock, splvm, spltty, splsofttty, splnet, splbio, splsoftnet, splsoftclock, spllowersoftclock, spl0, splx. This function would set the interrupt masks, while returning their previous contents. The splx routine could then be used to change the masks back.

  1. spl

    [abbrev, from Set Priority Level] The way traditional Unix kernels implement mutual exclusion by running code at high interrupt levels. Used in jargon to describe the act of tuning in or tuning out ordinary communication. Classically, spl levels run from 1 to 7; “Fred's at spl 6 today” would mean that he is very hard to interrupt. “Wait till I finish this; I'll spl down then.” See also interrupts locked out.
