Member Function Documentation

bool cDvbCiAdapter::Assign ( cDevice Device,
bool  Query = false 
) [protected, virtual]

Assigns this adapter to the given Device, if this is possible.

If Query is 'true', the adapter only checks whether it can be assigned to the Device, but doesn't actually assign itself to it. Returns true if the adapter can be assigned to the Device. If Device is NULL, the adapter 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'.

Implements cCiAdapter.

If Device is NULL, the adapter 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'.

virtual int cDvbCiAdapter::Read ( uint8_t *  Buffer,
int  MaxLength 
) [protected, virtual]

Reads one chunk of data into the given Buffer, up to MaxLength bytes.

If no data is available immediately, wait for up to CAM_READ_TIMEOUT. Returns the number of bytes read (in case of an error it will also return 0).

Implements cCiAdapter.
