# fetch_variable

### NAME

    fetch_variable - fetch a value stored in an object's global variable

### SYNOPSIS

    mixed fetch_variable(string variable_name, object ob | void);

### DESCRIPTION

    This efun returns the value stored in the global variable `variable_name` 
    in ob.

    `variable_name` is name of the global variable.
    `ob` defaults to this_object() if not specified.

    If `ob` is not specified, then `variable_name` can be any global variable
    in the inheritance hierarchy, regardless of scope.  If `ob` is specified,
    then `variable_name` must be public scope. 

    This is a potential security hazard and, therefore, you may wish to overload
    this function to perform security checks.

### EXAMPLE

    int weight = fetch_variable( "weight", this_player() ) ;
    printf("%d\n", weight") ;
    
    // result: 150
