Re: Carob on a Mac

Hi Ian,
So, for one email, you get three in return... good investment :)

Mine is about signals:
We can definitly *not* modify the message handler because we are a 
library... otherwise we must set it before each send() and put the old 
one back just after... "oh la la" :)
For freebsd and MacOs (>10.2), there seems to be an equivalent: 
SO_NOSIGPIPE
This flag must be set at socket creation time by setsockopt but should 
be what we are looking for.
An solution proposed by Marc, which is quite elegant (I mean, the 
solution ;) ) could be to define 2 global variables in a 
system-definitions.hpp: one for socket options, one for send() flags

Everybody ? comments ?
