Please use mode_t and S_I???? macros instead of numeric modes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.Use:
-------------------------------------------------------------------------------
mode_t mode = S_IRWXU | S_IRGRP | S_IROTH;
-------------------------------------------------------------------------------
.Instead of:
-------------------------------------------------------------------------------
int mode = 0744;
-------------------------------------------------------------------------------
Note that S_IREAD, S_IWRITE and S_IEXEC are obsolete, you should use S_IRUSR,
S_IWUSR, S_IXUSR instead.
