Subject: sockets.c: Use size_t for iovec length
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=4efb424352d94a8b1aa638618f3d19c7f8dc575a;p=unikraft%2Flibs%2Flwip.git

sockets.c: Use size_t for iovec length

This change updates the lwip socket read/write ops to use unsigned
size_t for the length of the passed-in iovec.

The internal lwip read/write functions still use int, and simply package
it into struct msghdr, which is size_t once again.
If overflow is a concern we should fix it with a build patch.
