Lines: 13 Under 4.2BSD, use ``bzero'' to clear out a block of memory: bzero(addr, count) caddr_t addr; int count; (where ``addr'' is the address of the first byte to be cleared, and ``count'' is the number of bytes). Beware >64K counts in kernel code; I think the 4.2 bzero handles this but the 4.2 bcopy does not. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci (301) 454-7690 UUCP: {seismo,allegra,brl-bmd}!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland
