This is with libvirt from CVS. They don't look like errors to me though...
------------
In function ‘open’,
inlined from ‘readFile’ at virsh.c:850:
/usr/include/bits/fcntl2.h:45: error: call to ‘__open_too_many_args’
declared with attribute error: open can be called either with 2 or 3
arguments, not more
/usr/include/bits/fcntl2.h:51: error: call to ‘__open_missing_mode’
declared with attribute error: open with O_CREAT in second argument
needs 3 arguments
The code in question is:
if ((fd = open(filename, O_RDONLY)) == -1) {
Not a newly created file, so mode isn't needed AFAICS.
------------
In function ‘read’,
inlined from ‘readFile’ at virsh.c:864:
/usr/include/bits/unistd.h:43: warning: call to ‘__read_chk_warn’
declared with attribute warning: read called with bigger length than
size of the destination buffer
The code in question is:
char buffer[1024];
char *new;
int ret;
if ((ret = read(fd, buffer, sizeof(buffer))) == 0)
break;
Also seems correct to me.
------------
Other warnings:
virsh.c: In function ‘cmdSchedinfo’:
virsh.c:1138: warning: ‘weight’ may be used uninitialized in this function
virsh.c:1140: warning: ‘cap’ may be used uninitialized in this function
For some reason gcc appears to have lots its ability to do the data flow
analysis to find out that these warnings are bogus. In any case the fix
is trivial:
