Uh... maybe. The manpage states (reformated to fit the mail): | CONFORMING TO | | These functions are GNU extensions, not in C or POSIX. They are also | available under *BSD. The FreeBSD implementation sets strp to NULL on | error. However, absence from standards doesn't necessarily mean it sucks. Compare stuff like openpty(). I have seen this function in musl, and I guess the other major libcs do provide it, too. At least, at work the other day I compiled a rather large collection of programs against uClibc (including upstart and dbus), and I never had a problem because of asprintf(), though I did have problems because of other things. (Some ptrace constants were missing - Yeah, upstart ptraces all the processes it starts, in order to detect daemonizations. OK, you could use a program like pidfilehack for that, but no.) Ciao, Markus
