Subject: Fix return value type of vde_send().
X-Git-Tag: release-1.0.18~5
X-Git-Url: https://www.tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=cfe6558d4ba4f572311aeafd62737f6f2692ad86

Fix return value type of vde_send().

The libvdeplug_dyn.h header file incorrectly declares the return type of
vde_send() to size_t, while in reality it is ssize_t.
