Re: [1003.1(2008)/Issue 7 0000177]: mismatch between example descriptionand code

Problem: line_max is declared as long. To use it as the array limit 
declarator it would have to be '#define line_max =0;' but then 
sysconf() couldn't be used to assign its runtime value. Suggested fix: 
change the line[line_max] declaration to 'char *line;' declaration with 
a malloc()/free() pair to assign line a value.

A better example:

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

void f()
{
   long line_max;
   FILE *fp;
       ...
   if ((line_max = sysconf(_SC_LINE_MAX)) <= 0) {
       line_max = LINE_MAX;
   }
   char line[line_max];
   while (fgets(line, line_max, fp) != NULL) {
       ...
   }
   return;
}

</pre>
