What the 'if (x = y >= z)' or 'if ((x = y) >= z)' does is that it ASSIGNS
the value of y to x, and then compares it against z. This is a shortcut
some people use, like
if ((new_fd = accept(...)) == -1)
{
printf("Couldn't get new connection: %s", sys_errlist[errno]);
exit(1);
}
/* do something using new_fd, which now contains the file
descriptor to the connection */
Basically, what it does is that it combines two different steps into
one, as the above if can be written as
new_fd = accept(...);
if (new_fd == -1)
{
...
Hope this clarifies this a little.
