    You have to provide a data type in here:

    %20[^ ]

    I don't know if it's legal to put nothing after the circumflex ^.

    I assume you want it to avoid whitespace blanks or what?

    the first line in the file is
    W1 44444 WingThing 20
    so i need to have
    a=W1
    b=44444
    c=WingThing
    why idont have that
    i told it to stop on space char
    ??
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #define false 0
    #define true 1
    
     
      
    int main()
    {
    
    	FILE *f;
    	
    	char a[20];
    	char b[20];
    	char c[20];
    	f=fopen("c:\\ware1.txt","r");
    	fscanf(f,"%20[^ ]%20[^ ]%20[^ ]%*c",a,b,c);
    	fclose(f);
    	return 0;
    }

    ok this works
    but i am sure if it ignores one char at the end or justthe rest chars
    i dont wont to stack the buffer with garbage
    ??
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #define false 0
    #define true 1
    
     
      
    int main()
    {
    
    	FILE *f;
    	
    	char a[20];
    	char b[20];
    	char c[20];
    	f=fopen("c:\\ware1.txt","r");
    	fscanf(f,"%20s%20s%20s%*c",a,b,c);
    	fclose(f);
    	return 0;
    }

    Just use fscanf() to take in the W1, as a string. It will automatically stop at the first space it comes to.

    Then use another %s for your next bit, etc.

    I wouldn't do the "ignore" thing. Take in what you want, and then handle it in the buffer for any particulars. Don't ask too much from fscanf() - it's liable to fail and leave your program mangled.

    Yes, it moves the file pointer as it scans, if that's what you are asking.
