DMX_ADD_PID
| int fd | File descriptor returned by a previous call to open(). |
| int request | Equals DMX_ADD_PID for this command. |
| __u16 * | PID number to be filtered. |
This ioctl call allows to add multiple PIDs to a transport stream filter previously set up with DMX_SET_PES_FILTER and output equal to DMX_OUT_TSDEMUX_TAP.
On success 0 is returned, on error -1 and the errno variable is set appropriately. The generic error codes are described at the Generic Error Codes chapter.
