Debian Programming :: How Can Use Chmod In Assembly X86

i wanna use chmod() in linux x86 [debian 3.7.2 x86] but i have some problem in function argv

look at this function:
Code: Select all int chmod(const char *path, mode_t mode);

and mode_t modes:
Code: Select all       S_ISUID  (04000)  set-user-ID  (set  process  effective  user   ID   on
                         execve(2))

       S_ISGID  (02000)  set-group-ID  (set  process  effective  group  ID  on
                         execve(2);  mandatory  locking,   as   described   in
                         fcntl(2);  take a new file's group from parent direcق
                         tory, as described in chown(2) and mkdir(2))

[code]...

i know there is some problem in ecx and mode_t value/
