Circular definition in C

Question

What I\'ve written is:

typedef enum _MyStatus
{
    MY_STATUS_OK = 0,
    MY_STATUS_GENERAL_ERROR = -1,

} MyStatus;

typedef MyStatus (*MyCallback)(MySettings *         


        

Answer 1

How about putting this line at the top:

typedef struct _MySettings MySettings;

This C FAQ: How can I define a pair of mutually referential structures? might be of use.
