Hi,

Ok heres my problem,

void func(unsigned char *tmp)
{
// BLAH BLAH
}

How do i find how many bytes tmp is taking up in memory:

the sizeof funtion returns 4 bytes, the reason being (i think) that it
is finding out how many bytes the pointer takes up in memory. I dont
want to use strlen(tmp) because the string may have a '\0' character.

Can someone tell me how to find out how many bytes tmp takes up in
memory, OR how to declare it so that sizeof(tmp) will return the correct
number?

thankz

D.
