I wouldn't say it *means* that, exactly, but I do think that this is a case where SIG_IGN is different from SIG_DFL even when the default action is to do nothing. To put it another way, there are two concepts here, both of which are getting turned into tenses of "ignore" in English. One is a handler of SIG_IGN; the other is SIG_DFL with a default action of "do nothing". The wording in wait(2) is, I believe, talking about only the SIG_IGN kind of ignoring. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
