Assignment 2.7 string_copy definition doesn't match test harness or solution code

[jackc]

The definition for string_copy:

Accepts a pointer to a string, a pointer to a buffer, and buffer's length. Copies string to the destination. The destination address is returned if the string fits the buffer; otherwise zero is returns.

This is similar to strncpy in C. But the provided solution is the equivalent of strcpy. And because the caller in the test harness doesn't provide the buffer length in rdx an implementation that implements the behaviour described in the book will not pass the test.

Thank you for reporting it, I am sorry for this inconsistency.
For now we can stay with an unsafe version with only two arguments (equivalent of strcpy) and once I submit the rest of assignments/answers I'll replace the code to match the book text.
