+ * getline() reads an entire line from stream, storing the address of the buffer
+ * containing the text into *buf. The buffer is null-terminated and includes
+ * the newline character, if one was found.
+ *
+ * If *buf is NULL, then getline() will allocate a buffer for storing the line,
+ * which should be freed by the user program. Alternatively, before calling getline(),
+ * *buf can contain a pointer to a malloc()-allocated buffer *n bytes in size. If the buffer
+ * is not large enough to hold the line, getline() resizes it with realloc(), updating *buf and *n
+ * as necessary. In either case, on a successful call, *buf and *n will be updated to
+ * reflect the buffer address and allocated size respectively.
