Topic: typedef in function definition has a problem (Read 5173 times) previous topic - next topic


The following program produces a compiler error (Arduino 0011 alpha):
struct foo{
 int    a;
 int    b;
typedef struct foo FOO;
FOO  myvar[21];
FOO *myFunct(){}
void setup(){}
void loop(){}

ERROR is: error: expected constructor, destructor, or type conversion before '*' token
If I change
<FOO *myFunct(){}>
<struct foo *myfunct(){}> it compiles just fine.



You need to put type definition inside a separate header file, as the function prototypes that are generated by the IDE are inserted above the typedef (but below pre-processor directives like #include).  This header can be another tab in your sketch; use the right facing arrow in the upper right of the IDE.
