[vlc-devel] Re: [vlc] patches

[Derk-Jan Hartman]

vlc-devel usually is the best place to sent patches

1st: Apparently there is some confusion over what is the correct way. 
We wil now do as Apple, who 1st try byte (char) [seems the BSD way] and 
then fallback to int (windows method?)

2: in sapserver we will only try byte (char) now. it's not portable 
anyways and we aren't working much on it anymore

3: I fixed that potential divide by 0. Have a standard delay of 1 is 
not a good thing in my eyes. Actually, I'm thinking of changing this 
param to be specified in ms instead of s. If you have 50 announces a 1 
sec delay will take you 50 seconds to update all your announces. That 
might be a bit much for some. Anyways not really a prioriy.
Could you please investigate a bit further what the problem is with 
usleep? I'd rather not replace it. I found something in google about an 
old bug in NetBSD that would cause usleep to return immediately if the 
input value was too large. Could you try to see if this may be the 
problem?

4: vcdx fixed. :)

Thank you for pointing out these issues. More patches to fix NetBSD 
issues are always welcomed ...
