I have an interesting problem.
I define,
typedef char *string;
char array[10];
string buf[10];
i=0;
while(1){
array=<assign_string>
buf[i]= array;
i++;
}
At each iteration i assign different strings. For instance, buf[0] should be "1111111111" buf[1] should be "2222222222" and so on. However when i assign "2222222222" when i=1, buf[0] also changes to "2222222222". What could be the problem?
The problem is that all entries in buf point to the same string - the one named array. So changing array will affect all buf entries.
You could fix this by allocating a new string for every iteration, e.g. your pseudo-code would become:
string buf[10];
i=0;
while(1){
buf[i]= strdup( <array_string> );
i++;
}
Make sure to free() all the strings when you're done using them.
You are probably not allocating a new string for each entry in buf. Instead you are saving a reference to the same string in each buf entry.
When you do buf[i]=array; you put the address of your char array[10] into buf[i].
No suprise, each buf[i] has the same address and the same value.
