Aucbvax.1522 fa.unix-wizards utzoo!duke!decvax!ucbvax!day@RAND-UNIX Thu Jun 4 21:31:13 1981 405 overlays There is a little-known less-understood feature for text overlays in the V7 kernel, where an exec of a binary with a 405 magic number will bring in a new text segment, leaving the data segment alone. You know, `chain'. Does anyone have a version of ld.c that can make decent use of this facility, or is there some tricky way to get vanilla ld to do what you want? --dave ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
