I have a struct like this:
struct A
{
char x[];
};
What does it mean? When I do something like:
A a;
a.x = "hello";
gcc throws an error saying:
error: incompatible types in assignent of 'const char [6]' to 'char [0u]'
This is a C99 “flexible array member”.
See here for gcc specifics: http://www.delorie.com/gnu/docs/gcc/gcc_42.html
