c - Errors in header file with function taking structs -

-

what's wrong header? gcc throws out:

 libmmbox.h:7:29: error: expected ‘)’ before ‘*’ token  libmmbox.h:8:27: error: expected ‘)’ before ‘*’ token

here's code:

#ifndef __libmmbox_h__ #define __libmmbox_h__  int mmbox_connect(char *username); int mmbox_login(int token, char *password); int mmbox_quit(); int mmbox_stat(mmbox_stat_t *result); int mmbox_list(mmbox_mail **l, int *num_msg); int mmbox_send(char *dest, char *obj, void *buf, size_t size); int mmbox_rcv(int id, void *buf, size_t size); int mmbox_delete(int id); int mmbox_resume(int id);  typedef struct {     char *user;          int used_space;      int free_space;      int num_msg;     } mmbox_stat_t;  typedef struct  {     char *sender, *recipient; /     char *obj, *date;              char flags;                           size_t size;               } mmbox_mail;  #endif

mmbox_stat_t struct declared after used function signature. compiler doesn't still know type when declare:

int mmbox_stat(mmbox_stat_t *result);

put function prototypes after data structures definition.
