Subject: [PATCH] net/socket: Fix compiler warning (regression for MinGW)
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

||
Content-Transfer-Encoding: 8bit

||
Commit 213fd5087e2e4e2da10ad266df0ba950cf7618bf removed a type cast
|
||
which is needed for MinGW:
|
||
|
||
net/socket.c:136: warning:
|
||
pointer targets in passing argument 2 of ‘sendto’ differ in signedness
|
||
/usr/lib/gcc/amd64-mingw32msvc/4.4.4/../../../../amd64-mingw32msvc/include/winsock2.h:1313: note:
|
||
expected ‘const char *’ but argument is of type ‘const uint8_t *’
|
||
|
||
Add a 'qemu_sendto' macro which provides that type cast where needed
|
||
and use the new macro instead of 'sendto'.
