Hi all,

Problem:
I have a pointer to an unsigned char, i put a char into the variable the
pointer is pointing to, push it to some outputs and nothing happens....
Example code:
...
unsigned char * stream;
stream = (unsigned char *) malloc(1);
if(stream == NULL)
return NULL;
*stream = (unsigned char) getchar(); // getchar returns just a char
P2 = *stream;
...
Nothing apears on the output port P2...
It has something to do with the pointer thats for sure, the assembly code is
correct and if i replace the getchar function by a value it doesnt work
either...
It looks like i just cant write a value to the variable the pointer is
pointing to.
Now the following for example works:
unsigned char stream = 0xaa; // just an example value
P2 = stream;
Any thoughts?
Cheers
Bart
