Proxy scheduler parameters for background channel switching.
This structure is passed along with channel change requests for clients with priority VBI_CHN_PRIO_BACKGROUND
. The parameters are used by the proxy daemon to share channel control between multiple clients with background priority.
uint8_t vbi_channel_profile::is_valid |
Boolean: Ignore contents of this struct unless TRUE
uint8_t vbi_channel_profile::sub_prio |
Sub-priority for channel scheduling at "background" priority. You can use aribtrary values in the range 0 ... 256, but as this value is only meaningful in relation to priorities used by other clients, you should stick to the scale defined by VBI_CHN_SUBPRIO
uint8_t vbi_channel_profile::allow_suspend |
Boolean: Set to FALSE if your capture client needs an atomic time slice (i.e. would need to restart capturing from the beginning it it was interrupted.)
time_t vbi_channel_profile::min_duration |
Minimum time slice your capture client requires. This value is used when multiple clients have the same sub-priority to give all clients channel control in a round-robin manner.
time_t vbi_channel_profile::exp_duration |
Expected duration of use of that channel
