C++ (Cpp) register_mon_chain Examples

Example #1

/***********************************************************************
F* Function:     static int wd_ioctl(struct inode *node, struct file *filp,
                             unsigned int cmd, unsigned long arg) P*A*Z*
 *
P* Parameters:   struct inode *inode
P*                - Passed by the kernel, inode of the device file being
P*                  operated on
P*               struct file *file
P*                - Passed by the kernel, but not used
P*               unsigned int cmd
P*                - ioctl command number
P*               unsigned long arg
P*                - Pointer to arguments cast to unsigned long.
P*                  The actual parameter depends on the command, see
P*                  wd(4).
P*
P* Returnvalue:  int
P*                 - 0 => success
P*                  <0 Errorcondition, which can be
P*                  -EINTR  the call was interrupted
P*                  -EFAULT the pointer passed as arg is invalid
P*                  -EINVAL a parameter was invalid
 *
Z* Intention:    This is the entry point for the ioctl() commands.
Z*               For a detailed description see the man-page wd(4).
