Thread: File Reading and storing to 1 variable

im trying to read a full file using fscanf and storing it to 1 variable
inside the file i have tried i few tests like

test test test
test test test
test test test

i can only get it to read 1 of the tests.is there a simple way to read the entire file and store it to one variable?
thanks

thanks thats helped a fair bit i was stuck on fscanf
its for a win32 unicode app.
im wondering is there a unicode function for fread?

Code:

if(fread(&ReadTxt , sizeof(ReadTxt) , 1 , fal)){
			if(feof(fal)){
				break;
			}
		}

fal is the file.

i am doing this and then having a messagebox show it and its comming up with alot of messy wide chars.

how would i do that(sorry ive only been doing C a lil while)

also i done it in a normal C app as

Code:

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
  FILE *fp;
  char test[2048];
  fp = fopen("test.txt" , "r");
  
  
  	while(fp != feof){
    		fread(&test , sizeof(test) , 1 , fp);
    		break;
   }  
    printf("%s" , test);
    getch();
}

it reads the file fine but adds a few unwanted chars to the end.
in the unicode winapi program it didnt even get one bit of it right

beats me how but i accidently added a number to the arraysize on the C version and it worked

Code:

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
  FILE *fp;
  char test[12048];
  fp = fopen("test.txt" , "r");
  
  
  	while(fp != feof){
    		fread(&test , sizeof(test) , 1 , fp);
    		break;
   }  
    printf("%s" , test);
    getch();
}

but i still cant get it to work in my unicode version(win32 api program)

use fseek to seek to the end of the file
use ftell to grab the position there
fseek back to the beginning
fread your entire file (it is possible that fread will set the file position no farther than the end of the file, so that earlier fseek might not be necessary)
then set the position obtained from ftell in your buffer to 0

im not to sure how to use fseek or ftell

ive looked throu google with not to much luck.
could u maybe please make a small example or point me to a link.thanks

thanks for the example.
still not working thou , heres what i tried.

Code:

		fseek(fal, 0, SEEK_END);
		pos = ftell(fal);
		fseek(fal, 0, SEEK_SET);
		fread(&ReadTxt , sizeof(ReadTxt) , 1 , fal);

pos is int

damn this is confusing.sorry for my stupidness but i dont no how to do this

i dont quiet understand fread right is it

fread(variable , eof , startof , file);

?
