need help in passing filename as a parameter

[ektubbe]

Hi Folks..
I need your help with following snippet :

#include <stdio.h>
void  ASCII_to_EBCDIC( size_t, unsigned char *);
void  EBCDIC_to_ASCII( size_t, unsigned char *);
void to_ASCII(unsigned char *);
void to_EBCDIC(unsigned char *);
/* conversion tables */
static  unsigned char

    inSituEbcdicToAscii (str);
    printf ("%s\n", str);
    return 0;
}

The above snippet is for a buffer/string, where as i want to pass file name as a parameter and want function to process the file line by line,can anyone plz help?

In the second link sample you will need to replace stdin with your file pointer
