problem with -> notation and using a "general" header file

Hey guys,
I am trying to get a grasp on using the '->' notation which I think, I slowly do understand. However, in the CheckString function, where I am trying to assign three different things to different pointers, I get errors. The file has a 3 digit number, a boat name (can consist of more than one name - not the name of the class though) not longer than 30 chars long, and a boat type which is represented as a string but given as a enum in the header.

The errors I had are as follows:

Code:

regatta.c:27: two or more data types in declaration of `main'
regatta.c:27: function definition declared `typedef'
regatta.c: In function `CheckString':
regatta.c:105: parse error before `Participants'
regatta.c:107: parse error before `int'
regatta.c:107: `i' undeclared (first use in this function)
regatta.c:107: (Each undeclared identifier is reported only once
regatta.c:107: for each function it appears in.)
regatta.c:107: parse error before `)'
regatta.c:115: parse error before `strcpy'
regatta.c:125: warning: passing arg 1 of `strcpy' makes pointer from integer wit
hout a cast
regatta.c:125: warning: passing arg 2 of `strcpy' makes pointer from integer wit
hout a cast
regatta.c: At top level:
regatta.c:129: parse error before `->'

line 27 is my main line. and the rest is the actual CheckString function.

Code:

char * CheckString( char *ptrdata )
{
	Boat *boatptr;
	BoatType *Typeptr;

	/*temporary variables for read strings*/
	char *ptrSail, *ptrClassType, *ptrBoatName;

	boatptr = Participants[ 0 ];

	for( int i = 0; i < 80; ++i )
	{
		if( isdigit( ptrdata[ i ] ) != 0 )
			strcpy( ptrSail[ i ], ptrdata[ i ] );

		if( isalpha( ptrdata[ i ] ) != 0 )
		{
			if( strstr( ptrdata, "Gwen" )
				strcpy( *ptrClassType, *ptrdata );

			/*if boat type is Thorpe copy what follows from that point onwards*/
			else if( strstr( *ptrdata, "Thorpe" )
				strcpy( *ptrClassType, *ptrdata );
			/*if boat type is Skiff copy what follows from that point onwards*/	
			else if( strstr( *ptrdata, "Skiff" )
				strcpy( *ptrClassType, *ptrdata );

			/*else it is the boat name so copy to pointer*/
			strcpy( *ptrBoatName, *ptrdata );
		}		
	}

	boatptr->SailNum = ptrSail;
	boatptr->BoatName = ptrBoatName;
}

Sorry if its getting too long. I just wanted to keep it as simple as possible. Thanks for your help in advance. Appreciate any kind of help.
Ta,

Thanks for that. I always muck up that strcpy syntax. Alos I just found an example that I could go something like this:

Code:

strcpy( someptr->ptrBoatType, ptrBoatType );

is that possible in this manner? thanks. I ll fix up those errors.Ta,
Johannes

Do you know why it gives me those errors? I dont see where it could get them from. I have put the function prototypes back into the main .c program and changed a few things with the return types as I dont think I need them, using ptrs and linked lists.
Here an extract of the error messages and the function that it complains the most about:

Code:

regatta.c:30: two or more data types in declaration of `CreateMaster'
regatta.c:91: `CreateMaster' redeclared as different kind of symbol
regatta.c:30: previous declaration of `CreateMaster'
regatta.c: In function `CheckString':
regatta.c:127: parse error before `Participants'
regatta.c:140: warning: passing arg 1 of `strstr' makes pointer from integer wit
hout a cast
regatta.c:143: warning: passing arg 1 of `strstr' makes pointer from integer wit
hout a cast

Code:

void CheckString( char *ptrdata )
{
   Boat *boatptr;
   BoatType *typeptr;

   /*counter*/
   int i, j = 0;

   /*temporary variables for read strings*/
   char *ptrSail, *ptrClassType, *ptrBoatName;

   /*allocate space for pointers*/
   ptrSail = malloc( sizeof *ptrSail );
   ptrClassType = malloc( sizeof *ptrClassType );
   ptrBoatName = malloc( sizeof *ptrBoatName );
   boatptr = malloc( sizeof( Boat ) );
   typeptr = malloc( sizeof( BoatType ) );

   boatptr = Participants[ j ];

   for( i = 0; i < 80; ++i )
   {
      if( isdigit( ptrdata[ i ] ) != 0 )
         strcpy( boatptr->SailNum, ptrdata );

      if( isalpha( ptrdata[ i ] ) != 0 )
      {
         if( strstr( ptrdata, "Gwen" ) )
            strcpy( ptrClassType, ptrdata );

         /*if boat type is Thorpe copy what follows from that point onwards*/
         else if( strstr( *ptrdata, "Thorpe" ) )
            strcpy( ptrClassType, ptrdata );
         /*if boat type is Skiff copy what follows from that point onwards*/
         else if( strstr( *ptrdata, "Skiff" ) )
            strcpy( ptrClassType, ptrdata );

         /*else it is the boat name so copy to pointer*/
         strcpy( boatptr->BoatName, ptrdata );
      }
   }
   ++j;
}

Thanks heaps for having a look at the stuff. Ta,
Johannes
