Error compiling smtp.c in struct smtpSink - I don't see any problems with the syntax?

[DayOldPorridge]

I'm still a bit of a C newbie, so there might be a few beginner mistakes.

When I try to compile my smtp.c file, it gives me these errors:

In file included from smtp.c:3:
/home/dominique/smtp/smtp.h:11: error: expected ‘)’ before ‘*’ token
/home/dominique/smtp/smtp.h:12: error: expected ‘;’ before ‘void’
smtp.c: In function ‘main’:
smtp.c:82: error: redefinition of ‘l_psmtpClient’
smtp.c:9: error: previous definition of ‘l_psmtpClient’ was here
smtp.c:141: error: redefinition of ‘l_psmtpClient’
smtp.c:82: error: previous definition of ‘l_psmtpClient’ was here

The error about the header file really puzzles me, because I don't see anything wrong with the syntax in smtp.h:

// smtp.h
#define NSMAIL_OK 0

int l_retCode;

typedef struct smtpClient smtpClient_t;

typedef struct smtpSink 
{
   void * pOpaqueData;
   void (*bdat)(smtpSink_t * in_psmtpSink, int in_responseCode, const char * in_responseMessage) ;
   void (*connect)( smtpSink_t * in_psmtpSink, int in_responseCode, const char * in_responseMessage ) ;
   void (*data)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*ehlo)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_serverExtension );
   void (*ehloComplete)(smtpSink_t * in_psmtpSink );
   void (*expand)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_emailAddress );
    void (*error)( SMTPSinkPtr_t in_psmtpSink, 
         int in_responseCode, 
         const char * in_errorMessage );
   void (*expand)( SMTPSinkPtr_t in_psmtpSink, 
         int in_responseCode, 
         const char * in_emailAddress );
   void (*expandComplete)(smtpSink_t * in_psmtpSink);
   void (*help)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_helpMessage );
   void (*helpComplete)(smtpSink_t * in_psmtpSink );
   void (*mailFrom)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*noop)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*quit)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*rcptTo)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*reset)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*send)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*sendCommand)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
   void (*sendCommandComplete)(smtpSink_t * 
         in_psmtpSink );
   void (*verify)( smtpSink_t * in_psmtpSink, 
         int in_responseCode, 
         const char * in_responseMessage );
}smtpSink_t;

Could anyone point out what I'm doing wrong?

Thanks for your help, in advance.

I guess the error is in smtp.c where you have your main(), and not in smtp.h. So, show us that piece of code.

You can't use the typedef'd smtpSink_t within the actual typedef. Replace it with struct smtpSink and it will work.
