Standard for typedef'ing

Question

gcc 4.4.4 c89

I am just wondering is there any standard that should be followed when creating types.

for example:

typedef struct date
{
} dat         


        

Answer 1

You may just simply use

typedef struct toto toto;

1. The struct toto (tag) and the typedef name toto (identifier) are in different C "namescopes" so they are compatible, but they point to the same type in the end.
2. As an extra bonus this is also compatible with C++, which usually implicitly has such a typedef.
3. As another bonus this inhibits to declare a variable toto which can be quite confusing at times.
