My global and local npm version for angular-cli is 1.0.0-beta.28.3 how do I upgrade that to.30? I tried @latest

My local package.json:
"devDependencies": {
    "@angular/cli": "1.0.0-beta.28.3",
    "@angular/compiler-cli": "^2.4.0",

My global package:

I see that the latest is beta.32 https://github.com/angular/angular-cli/releases
However when I run npm install -g angular-cli@latest it still installs.28.3

A:

In package.json I changed:
"devDependencies": {
   "@angular/cli": "1.0.0"

To:
"devDependencies": {
   "@angular/cli": "1.2.0"

 Q:

Is a return value of 0 from write(2) in C an error?

In the man page for the system call write(2) - 
ssize_t write(int fd, const void *buf, size_t count); 
it says the following:

Return Value
On success, the number of bytes
  written are returned (zero indicates
  nothing was written). On error, -1 is
  returned, and errno is set
  appropriately. If count is zero and
  the file descriptor refers to a
  regular file, 0 may be returned, or an
  error could be detected. For a special
  file, the results are not portable.

I would interpret this to mean that returning 0 simply means that nothing was written, for whatever arbitrary reason. 
However, Stevens in UNP treats a return value of 0 as a fatal error when dealing with a file descriptor that is a TCP socket ( this is wrapped by another function which calls exit(1) on a short count ):
ssize_t /* Write "n" bytes to a descriptor. */
writen(int fd, const void *vptr, size_t n)
{
    size_t      nleft;
    ssize_t     nwritten;
    const char  *ptr;

    ptr = vptr;
    nleft = n;
    while (nleft > 0) {

  Q: 

 Is a recurrence value of 0 from write(2) in C an error? 

 In the world page for the system call write(2) -
