Yes. The initial paragraph from it states pretty clear: Line 25639 [XSH errno] is explicit that "The setting of errno after a successful call to a function is unspecified unless the description of that function specifies that errno shall not be modified." However, free() does not mention its interaction with errno. -- http://ache.vniz.net/ _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
