cCamSlot::cCamSlot | ( | cCiAdapter * | CiAdapter | ) |
Creates a new CAM slot for the given CiAdapter.
The CiAdapter will take care of deleting the CAM slot, so the caller must not delete it!

void cCamSlot::AddChannel | ( | const cChannel * | Channel | ) |
Adds all PIDs if the given Channel to the current list of PIDs.
If the source or transponder of the channel are different than what was given in a previous call to AddChannel(), any previously added PIDs will be cleared.

bool cCamSlot::Assign | ( | cDevice * | Device, |
bool | Query = false |
||
) |
Assigns this CAM slot to the given Device, if this is possible.
If Query is 'true', the CI adapter of this slot only checks whether it can be assigned to the Device, but doesn't actually assign itself to it. Returns true if this slot can be assigned to the Device. If Device is NULL, the slot will be unassigned from any device it was previously assigned to. The value of Query is ignored in that case, and this function always returns 'true'.

bool cCamSlot::CanDecrypt | ( | const cChannel * | Channel | ) |
Returns true if there is a CAM in this slot that is able to decrypt the given Channel (or at least claims to be able to do so).
Since the QUERY/REPLY mechanism for CAMs is pretty unreliable (some CAMs don't reply to queries at all), we always return true if the CAM is currently not decrypting anything. If there is already a channel being decrypted, a call to CanDecrypt() checks whether the CAM can also decrypt the given channel. Only CAMs that have replied to the initial QUERY will perform this check at all. CAMs that never replied to the initial QUERY are assumed not to be able to handle more than one channel at a time.
