* Name: ioctl
|
|
*
|
|
* Description:
|
|
* Perform device specific operations.
|
|
*
|
|
* ioctl() is a non-standard UNIX-like API
|
|
*
|
|
* Input Parameters:
|
|
* fd File/socket descriptor of device
|
|
* req The ioctl command
|
|
* arg The argument of the ioctl cmd, OR
|
|
* ... A third argument of type unsigned long is still expected.
|
|
*
|
|
* Returned Value:
|
|
* >=0 on success (positive non-zero values are cmd-specific)
|
|
* -1 on failure with errno set properly:
|
|
*
|
|
* EBADF
|
|
* 'fd' is not a valid descriptor.
|
|
* EFAULT
|
|
* 'arg' references an inaccessible memory area.
|
|
* EINVAL
|
|
* 'cmd' or 'arg' is not valid.
|
|
* ENOTTY
|
|
* 'fd' is not associated with a character special device.
|
|
* ENOTTY
|
|
* The specified request does not apply to the kind of object that the
|
|
* descriptor 'fd' references.
