Metrics overview

Globals Modified

API ID: CountGlobalsModified
Languages: C, C++, Pascal, Python, Web
Targets: Functions

The number of modifications to global objects by this function

Example:

    int my_global = 10;
    void modifies(int x)
    {
      int y, z;
      x += 1;           //     Parameters do not count
      x ++;             //     Parameters do not count
      y += 1;           //     Locals do not count
      y ++;             //     Locals do not count
      my_global += 1;   // + 1 Globals count
      my_global ++;     // + 1 Duplicates count
    }                   // CountGlobalsModified = 2
