Thread: Confusion with typedef

Code:

typedef int (*test) ( float * , float*)
test tmp;

what is the type of tmp, is it int ?

Code:

typedef int (*(*f)(int (*)(int)))(int (*)(int));

Ruh roh, Shaggy!!

No, the type of tmp is the one which precedes it, 'test' in this case.

the typedef statement defines an alias for an already existing datatype or to create a new user defined datatype.

Code:

eg:
typedef int ud_int;
ud_int var1;

Here, ud_int is a user defined datatype which is similar to int.

On the same lines,

Code:

typedef int (*test) ( float * , float*)

'test' is the new datatype which you have defined and 'test' happens to be a pointer to a function which accepts two arguments of type float and returns an integer.

Check this link below for more details on function pointers.
