Unfortunately the direct cast to void doesn't suppress the warning. I tried that first before using the variable assignment (which then required a cast to void to avoid an unused variable warning!)
Ideally, you should actually check the return value to make sure there wasn't an error (-1 returned) or an incomplete write (the number of bytes written is less than the count argument).

There is now a compiler warning when the return value of write() is ignored. This causes errors in a number of placees in nginx. I have included a log showing the compiler output as well as a patch file showing the changes I made to avoid these errors.
However, there is more elegant way to suppress this warning without
Could you test the attached patch ?
