I'm wondering about the difference between what is defined by the several standards of the C language and the things that every compilers implements in a different way from the others, i want to really understand what the official specs of the C language are: there are some official docs?
I'm looking for technical stuff, not a thread on the internet, some good pdfs maybe; something that can describe everything happens with the memory management, the allocation, the lenght and the encoding of the variables, etc etc ...
I have the official manual from K&R but it's not really about what i am interested to, it's more on the "programmer side" i want something more technical and affermative.
PS the C language have an official website for reference?
