src/lib/libc/gen/getnetgrent.c:169]: (warning) %s in format string (no. 1) requires 'char *' but the argument type is 'void'.


Source code is

       char buf[1024];
        (void) fprintf(stderr, "netgroup %s\n",
            _ng_print(buf, sizeof(buf), ng));

but

void
_ng_print(char *buf, size_t len, const struct netgroup *ng)
