help with output file from screen to csv file

[edwar]

have this code and when i run it, i get the output on the screen, what i would like to do is that i can see the output on the screen and
send it to an xls of cvs file. is there anyone
who could chage the code and let it working.

thanks for help
the code is :

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <memory.h>
typedef struct link
{
struct link *next;
char word[24];
int numTimesAppear;
}Link;

int CreateAllNodes(Link **, Link **);
void WalkNode(Link *);
int DestroyAllNodes(Link *);
int AddToList(Link **pTheHead, char *Word);

If you want the output to go to two places (screen and file) then you will have to print it twice. Put the code in a function then pass it the stream object (either an opened FILE* pointer or stdout)

Hi Ancient Dragon,

Thank you for you reaction but would you like to give me more detail about the founctie i have to do, i tried to make a new pointer with the name *OutPutfile but it doesn't work, please how could i do that.

thanks,

[Ancient Dragon]

simple example:

#include <stdio.h>

void foo( FILE* out )
{
    fprintf(out,"Hello World\n");

}

int main()
{
    FILE* fp;
    foo(stdout);
    fp = fopen("test.txt", "wt");
    foo(fp);
    fclose(fp);
    return 0;
}

Hi Ancient Dragon,
thanks again, but i don't like to print the out on a txt file or csv file,
what i would like to do is :
open or red a txtfiel, when the txtfile is open, i can see the content,
now i like to write a function to save the output to another file
for example txtfile.
in the code i have to open a textfile and read the content and sort the words and then save it to .csv file.
the code i have wrote, opens a textfile and reads the content of the textfiel and sorts the words but don't save the output. so that what i want to do.
