Consider the following scenario:
if(condition)
FOO();
else
bar();
Suppose FOO is defined as follows:
#define FOO() { bar(); baz(); }
Then it expands to the following:
if(condition)
// Syntax error, we are not allowed to put a semicolon at the end.
{ bar(); baz(); };
else
bar();
If we define FOO as follows:
#define FOO() do { bar(); baz(); } while(false)
Then it expands to the following:
if(condition)
do { bar(); baz(); } while(false);
else
bar();
Which is correct.
