Hi all,
I have a native application porting for Android by using bionic.
When I try to execute this native application the fstatfs() system
call returns -1 always and the errno is 22(EINVAL).
Any idea why this fstatfs() always returns -1 for Android. The same
application is running successful on X86 Linux but fails on Android
emulator.
Example code is
int main (void)
{
struct statfs buf;
int ret = 0;
int fd = 0;
fd = open("test.txt", O_RDWR | O_CREAT, 0700);
if (fd < 0)
{
printf("\n fd: %d ******* errno: %d *******\n ",fd, errno);
return 0;
}
printf ("\n fd: %d", fd);
ret = fstatfs(fd, &buf);
printf("\n ret: %d errno: %d \n ",ret, errno);
close(fd);
return 0;
}
output
fd: 3
ret: -1 errno: 22
