SMB mount fails with execl()

To mount CIFS presently I use system() call in source, this works. If I try to run command manually on shell it works too.

$ mount -t cifs //IP/dir /mnt -o user=name,pass=PASS,domain=mydomain,nounix
$ mount.cifs //IP/dir /mnt -o user=name,pass=PASS,domain=mydomain,nounix

But if i replace the same command with exec() family i see errors.

if(fork() == 0) 
{
  if (execl("/bin/mount", "/bin/mount", "-t", "cifs", "//IP/dir",  "/mnt", 
  "-o user=name,pass=PASS,domain=mydomain,nounix", (char*) NULL) < 0)
  ...
}
else
  ...

Error: mount: mounting cifs on //IP/dir /mnt failed: No such file or directory. It looks like mount directory "/mnt" is not recognized or not seen by mount process.

Tried below things but no luck:

What would be the cause here? How to see the command line parameters of the exec()'ed program ?

Version of mount:

mount.cifs version: 1.14-x

Used strace() to find the arguments passed to execl(). Solved my issue by using system calls mount() and umount().

Presuming you have installed samba

sudo apt-get install samba

In the Global section of the file /etc/samba/smb.conf you should have this :-

workgroup = WORKGROUP
netbios name = PCNAME
name resolve order = bcast host

Change WORKGROUP and PCNAME accordingly. Set the name resolve order as shown in order to browse windows shares using Nautilus.
