[Spice-devel] [PATCH] spicy: port_data: check write return value

[Uri Lublin]

Fixes the following build warning (but does not really check write return value):
spicy.c: In function ‘port_data’:
spicy.c:1711:10: error: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Werror=unused-result]

Alternatively, if we really care about writing port data to stdout:

-    write(fileno(stdout), data, size);
+    if (write(fileno(stdout), data, size) != size)
+        g_warning("Failed to write %d bytes to stdout", size);
