[erlang-questions] Question on "selective receive"

[Ludovic Demblans]

Hi,

You are talking about the 'after' clause of a receive expression. It can  
only have integers as clauses, starting from 0 to infinity, and a special  
value 'infinity' literally, which is the default.

So it cannot fail, these are not guards, it is just a time in  
milliseconds, and the receive expression value is the 'after' clause value  
if no pattern of the receive clause is satisfied in the duration.

(sorry for bad englih, i hope this is readable ;) )
