2 ways:

compile main program and linking wiht one command, all objects will be created and an executable will be created after all
1) gcc -o myprogram example-635.c cf_packet.c

My example works only for integers >= 0. if the input number is negative the is_digit will return -1 because of the "-".

It depencne what u want to do and what the program expect from user, u can...

in your main program to get 6 times user's input:


int res=0;
char user[100];

for(int i=1;i<=6;i++)
{
printf("for i=%d\n",i);
scanf("%s",user);

your function could be like this:


int is_digit(char* digit)
{
int len=strlen(digit);
for(int i=0;i<len;i++)
{
if(isdigit(digit[i])==false)
...

The values SIZE &SIZE2 are the same...

sorry man i don't have enough time but the first thing that i saw was your if statements. just change the '=' to '==' on your if's, to make them work and not changing fileInput[SIZE][SIZE2] values. 0...

check your if . must be if(something==1) and not if(something=1). The first if will check if something is equal but the second if will make something equal to 1 and then will check if something is...

On linux there is a tool called Valgrind with valkyrie as gui which has memcheck. It saved my life!!!!I was searching faults about weeks, using this program i found more mistakes than i expected. I...

I found the problem. I tested my accept function and it returns sometimes error, this makes fork twice. One check of returned value of accept fixed my prob.
i'm stupid sorry!!!!

Thanks a lot man for your answer. I was thinking about this but i don't know how and if the signal function is called. I put a sleep function on parent for 3 secs and it prints normal things. Now...
