Description

network_writev.c defines UIO_MAXIOV for various operating systems. In my case (IRIX 6.2), the value that was specified was incorrect, causing an EINVAL during a large writev.

I think the correct thing to do here is use sysconf to determine the correct value for the OS at runtime (since it can also vary).

Example: 

#include <stdio.h>
#include <unistd.h>

int main(int argc, char **argv) {
        printf("_SC_IOV_MAX: %d\n", sysconf(_SC_IOV_MAX));
        return 0;
}
