You can't put the attributes between the closing ) and the opening { in 
a function definition.

I tend to place them in front of the declarator. This is in line with C++11:

This enables you to replace some GNU-specific attributes with C++ 
attributes for example.

Also the C11 _Noreturn is in front of the function declaration:
