Uh... maybe. The manpage states (reformated to fit the mail):

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
