Re: Read line after line but from the eof.

Ground21 =D0=C9=D3=C1=CC(=C1):


Take it, i am slightly adapted it for C++ from C:
Declare in your program:

#include <stdio.h>

namespace NGround21
{
typedef unsigned int uint;

// store 'max_visible_chars' chars maximum to 'buf' and close by \0
//( ! ADD '\0' char to buf, total size can be 'max_visible_chars' +1
maximum )
// all 256 chars of DOS/Win/UNIX <EOL> allowed
//special: to skip all chars till <EOL> write:
getln(any_number,0,correct_pointer);

// "fi" must be open as "rb"
// return 0 if errors in parameters, else return !0
// "fi"filepointer will be after <EOL> if return !0
char getln(char *const buf, const uint max_visible_chars,FILE
*const fi)throw();

//namespace NGround21}

using namespace NGround21;

Write as separated cppfile, compile it and then link objectfileto
your project

#include <stdio.h>

char NGround21::getln(
              char *const buf,
              const uint max_visible_chars,
             FILE*const fp
           )throw()
{
    if(
       ( (max_visible_chars) && (!buf) )
       ||( !fp )
      )return 0;

char *p=buf;
    for( uint len=0; ; )
     {
      int ch=fgetc(fp);
      if( feof(fp) )break;

      if( ch==13 )continue;
      if( ch==10 )break;

      if( len >= max_visible_chars )continue;

      ++len;
      *p++=static_cast<char>(ch);
     }

   if( p ) *p=0;
   return 1;
