Why would they crash? Please explain to me the conditions, under which that happens. I tested them, and they don't crash. The change you made has the effect, that if the input is empty, or contains only spaces, then in the output no terminating zero is written (which makes it worse). My version crashes only in the following instances:
- the input pointer is not valid
- the input data contains no terminating zero
- the output pointer is not valid
- the output pointer points to a read-only area in memory
- the output pointer doesn't have enough memory to contain the result
all of those conditions are like in other string handling functions, like strcpy(). So if strcpy() works, trim_copy() should also work.
EDIT: oh, I see your problem now. I had a Typo in the first line, saying "char *end = ouput;". That was supposed to be "output". You probably just deleted the initialization, so that it crashed.
