Garbage being printed when using strcpy

Question

I have a function that will parse some data coming in. My problem is that after using strncpy I get some garbage when I try to print it. I try using malloc to make the char

Answer 1

One problem: What if there's no newline?

Undefined behaviour:

pos = strchr(temp_str, newline);
strcpy(temp_str, pos+1);

The source and destination of strcpy must not overlap.
