25 | // "classic" parser for unserializing OSContainer objects | |
26 | // | |
27 | // XXX - this code should really be removed! | |
28 | // - the XML format is now prefered | |
29 | // - this code leaks on syntax errors, the XML doesn't | |
30 | // - "classic" looks, reads, ... much better than XML :-( | |
31 | // - well except the XML is more efficent on OSData | |
32 | // | |
33 | // | |
34 | // to build : | |
35 | // bison -p OSUnserialize OSUnserialize.y | |
36 | // head -50 OSUnserialize.y > OSUnserialize.cpp | |
37 | // sed -e "s/stdio.h/stddef.h/" < OSUnserialize.tab.c >> OSUnserialize.cpp | |
38 | // | |
39 | // when changing code check in both OSUnserialize.y and OSUnserialize.cpp | |
