Subject: Handle EWOULDBLOCK at socket communication (#7596)
X-Git-Url: http://developer.intra2net.com/git/?a=commitdiff_plain;h=08059d7fb37e975616bac50945ba7b0d145c242e;hp=6f59dcf596103d0bc69be841627cd9926faa4139;p=libt2n

Handle EWOULDBLOCK at socket communication (#7596)

This adds treatment to the EWOULDBLOCK error on socket comms.
Previously only EAGAIN was treated.
