C reading from a live file ( file keep growing in size )

Question

I have an application that is recording live , the capture file keep growing in size using fread() and feof() , but feof() is breaking the loop early , so what's the best technique to keep reading from the stream

• should I wait and then I can advance the file stream ?
• should I open the file again and advance to position by calculating the total of read bytes?
• maybe something else ?

the code will have to read the file , build a packet and send it packaging and sending is going well with fixed size files

Answer 1

I would monitor the file (something like select(2)). When notified, I would read as much as possible then wait again.

well at the receiving side , do you know any simple video playback program written in C so I can implement select there too ? – Parttime
