[Qemu-devel] [PATCH 4/4] linux-user/syscall.c: remove wrong forward decl of setgroups() |
Date: |
Mon, 10 Dec 2012 07:59:46 +0100 |
this declaration is wrong:
the correct prototype on linux is:
int setgroups(size_t size, const gid_t *list);
since by default musl libc exposes this symbol in unistd.h
additionally to grp.h, the wrong declaration causes a build error.
the proper fix is to simply include the correct header.
