Subject: musl & strndupa?
Hi,
I'm trying to compile 'audit' (aka libaudit, auditd, etc - from
http://people.redhat.com/sgrubb/audit/index.html version 2.3.2). Using musl
0.9.14.
The file 'src/ausearch-lol.c' uses a reference to 'strndupa', which I
presume is an alloca version of strndup, and presumably a _GNU_SOURCE
feature. I can't seem to see a definition for it in musl, although strdupa
exists in string.h (Indeed, http://linux.die.net/man/3/strdup suggests as
much).
Is this intentional? If so, what would anyone suggest as a work around? My
guess would be #define strndupa(x, t) strncpy(alloca(strlen(x)+1),x,t)
but I'd like a second opinion...
Raph
