You only send 4 bytes down the socket. Why are you trying to read 30?Replace with:Code:char *passpointer;
int hasnull;
int letras;
passpointer = buff;
for(i=0;i<strlen(buff)+1;i++) {
if(passpointer != '\0') {
passpointer++;
letras++;
}
else {
hasnull=1;
}
}
printf("has null?: %i Letras: %i\n", hasnull, letras);
Code:printf("has null?: yes, eventually Letras: %lu\n", (unsigned long) strlen(buff));
