Minimal tail on windows ce arm

Hi all, please i’m looking to compile a minimal version of tail.
I installed visual studio 2008 and colibri package. Now i’ve to compile the software but i can’t fine commands like:

lseek or read.

the compiler does’nt recognize library to include like io.h

Any idea?

Hi Alex! Thanks!

I know the functions! I was only trying to use the same LINUX stdlib instructions, now i’ve upgraded the software in these way ( formatted also the computer dyed for a trojan ):


// minitail2.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#define _FILE_OFFSET_BITS 64
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
//#include <winbase.h>
//#include <fcntl.h>
//#include <errno.h>
//#include <unistd.h>
//#include <getopt.h>

#define BUFF_SIZE 10000
FILE *file;
unsigned int lung;
unsigned int nbyter;
char c;
char buff[BUFF_SIZE+1];

int _tmain(int argc, _TCHAR* argv[])
//int _tmain(int argc, unsigned char* argv[])
	//fprintf( stdout, "numero dei parametri: %d\r\n", argc);
	if ( argc != 3 ) {
		fprintf( stderr, "Utilizzo errato\r\nCorretto uso:\r\n minitail <numerobyte da inviare> <nomedelfile>");
	sprintf( buff, "%s", argv[2]);
	//sprintf( buff, "param99.txt");
	file= fopen(buff, "r");
	if ( file == NULL ) {
		fprintf(stderr, "errore aprendo il file [%s]\n", buff);
		exit (1);
	// ok aperto correttamente
	fseek( file, 0, SEEK_END);
	lung = ftell(file);
	sprintf( buff, "%s", argv[1]);
	nbyter = atol(buff);
	//nbyter = 2000l;
	fprintf( stdout, "Lunghezza file: %lu byte indietro: %lu \r\n", lung, nbyter);
	if ( lung < nbyter ) {
		fseek( file, 0, SEEK_SET);
	} else {
		fseek( file, -nbyter, SEEK_END);
	//fprintf( stdout, "Nuova posizione file: %lu\r\n", ftell(file));
	//WalkWFile(file );
	while ( fread( buff, 1, 1, file) > 0 ) {
		if ( buff[0] == '\n' ) {
	//printf( "inizio lettura\r\n");
	// bene ora leggo le righe
	while ( fgets( buff, BUFF_SIZE, file) != NULL ) {
		printf( "%s", buff);
	printf( "\r\n");
	fclose( file);
	return 0;

BUT now the compiler says that is unabled to compile for colibri ARM

I tried to compile it and everything went well.
