I'm not sure whether the second is illegal or not, but in any case it
doesn't make any sense (so I can't be bothered to look it up). In
both cases, customStruct is the *structure* tag, not a type name.
If you wanted to use a typedef, it would be more like:
typedef struct customStruct {
int RecID;
char *Name;
} customType;

If you're sticking to strictly ANSI C like this, the comp.lang.c
newsgroup is a good place to go. More useful is its FAQ, which
you can find at "http://www.eskimo.com/~scs/C-faq/faq.html";. There
are other newsgroups on C, including one for learners, but I don't
have the precise name at hand.
A good book might be a better bet, though. Both Kernighan & Ritchie
and Harbison & Steele have discussions of typedefs that show how to
use them with structures.
Good luck.
