It's fairly typical behaviour on Unix systems (may even be POSIX, not sure). And no, there isn't. > It seems that this will create potential bugs wherever a program passes > a filename to libxml2 without checking it first; if the filename is "-" > then libxml2 will attempt to read from stdin and the program may block > indefinitely. Sure - but so would CON under windows, or /dev/stdin, or /dev/ttys7, ... Reading input in a blocking condition is not a problem for libxml2; it's up to the users to prevent such cases if it's important for them. If you're using the library, you could always freopen stdin from /dev/null (or dup fd 0, not sure if libxml2 uses the stdin FILE*) - that would prevent libxml2 from blocking if someone passed "-" (but the other cases listed above would still cause trouble). Or you could filter user-supplied names and reject "-" and "/dev/*", which should catch most cases of blocking input. _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] http://mail.gnome.org/mailman/listinfo/xml
