It is easy
you would charge file to RAM (array, count the line of file for array size), after you change the value, you would write the file again.
int line_count(FILE *fp)
{
int count=0;
char letra;
letra=getc(fp);
while(!feof(fp))
{
if(letra=='\n')
{
count++;
}...
I think that : Santoku-linux can help too, Santoku includes a number of open source tools dedicated to helping you in every aspect of your mobile forensics, malware analysis, and security testing needs. You can decompile application to learn.

This is the function:
input: string (texto)
ouput: int
int deBinario(char * texto){
int longitud = strlen(texto);
int valorMenosSignificativo = texto[longitud - 1] - '0';
texto[longitud - 1] = 0;
if (longitud == 1)
return valorMenosSignificativo;
else
return...
A structure is a collection of one or more variables, possibly of different data types... Array has same data type.
To copy structure content into another structure is easy
a=b;
In arrays "for" is mandatory for copy (memset is possible).

Use strtok() for example
#include <string.h>
...
char *token;

char *search = " ";
/* Token will point to "LINE". */
token = strtok(line, search);
/* Token will point to "TO". */
token = strtok(NULL, search);

You can make a script using the ping command and run it every minute scheduled in the crontab to see if internet failure.
ping -c4 router | grep 'received' | awk -F',' '{ print $2}' | awk '{ print $1}'
where router is router ip. For example.
ping -c4 192.168.1.1 | grep 'received' | awk -F','...
false mode w
w Create for writing. If a file by that name already exists, it will be overwritten.
is better
FILE *fp;
fp=fopen("filename.txt","r+"); //Open an existing file for update (reading and writing).
if(fp==NULL) //If a file by that name NO...
