hi there, i was wondering about this for some time now: various documents decribe different policies regarding exit(3)'s return values. style(9) e.g. recommends using exit(0), while other man pages such as err(3) recommend using the sysexits(3) return values. i think i read some time ago on the mailinglists that it was decided that exit(3) should return integers rathers than sysexits(3) values. is this correct? shouldn't then all references such as in err(3) be removed and a note added to sysexits(3) that returnings its values via exit(3) does not according to current FreeBSD programming style? cheers. alex -- a13x
