Thread: Function overloading by passing structure variable

Hi folks,
This is my code. I don't know what error in this. Please help me to correct it

Code:

struct m_Record
  { 
    int number;
    char S_trancode[3];
    char S_sectype[5];
    char S_secsym[8];
    char D_tdate[9];
    char D_sdate[9];
    int N_quantity;
    int N_trdamt;
    char S_sourcetype[5];
    char S_sourcesym[8];
}mRecord;

struct inx_Record
{ 
    int number;
    char D_tdate[9]
}inxRecord;

// read a record from the main
int ReadRecord(FILE *File, int RecNum, struct m_Record Record)
  { if( fseek(File, RecNum * sizeof(Record), SEEK_SET) == 0 )
      if ( fread(&Record,sizeof(Record),1,File) )
        return 1;
    return 0; }

// read a record from the index file
int ReadRecord(FILE *File, int RecNum, struct inx_Record Record)
  { if( fseek(File, RecNum * sizeof(Record), SEEK_SET) == 0 )
      if ( fread(&Record,sizeof(Record),1,File) )
        return 1;
    return 0; }

void ListRecords(FILE *File,struct m_Record Record )
{ 
    int i = 0;
        tcnt=0;    
        while (ReadRecord(File,i,Record))
          { 
        if (Record.number != -1)
        {
            printvalues();
            tcnt++;
        }
        
            i++; 
    }
        printf("\n\n");
    printf("Total Records : %ld",tcnt);
    printf("\n\n"); 
}

void ListRecords(FILE *File,struct inx_Record Record )
{ 
    int i = 0;
        tcnt=0;    
        while (ReadRecord(File,i,Record))
          { 
        if (Record.number != -1)
        {
            printvalues();
            tcnt++;
        }
        
            i++; 
    }
        printf("\n\n");
    printf("Total Records : %ld",tcnt);
    printf("\n\n"); 
}

/////////// in my main function i will call the ListRecords() function as below
FILE *File;
c=toupper(getchar());
    switch(c)
    {
        case '1' :
            File = FileOpen(FNAME);
            break;
        case '2' :
            File = FileOpen(TEMPF);
            break;
    }
        if (!File)
          { 
        printf("Curses foiled again!\n\n");
            exit(-1); 
    }
if (c=='1')
    ListRecords(File,mRecord);
 else
     ListRecords(File,inxRecord);

i got the below error

Code:

difffiles.c:69:5: error: conflicting types for ‘ReadRecord’
difffiles.c:62:5: note: previous definition of ‘ReadRecord’ was here

difffiles.c:187:6: error: conflicting types for ‘ListRecords’
difffiles.c:168:6: note: previous definition of ‘ListRecords’ was here

You can't overload functions in C.


Quzah.

You might just want to be getting a good book on C programming and read it cover to cover...
I get the feeling the review could save your company.

To put it bluntly, but in all due respect... have you not yet realized that you are hopelessly out of your depth here?
