+ * to freeing the dynar. This can be done by simply freeing the first argument
+ * of the dynar:
+ * free(xbt_dynar_get_ptr(dynar,0));
*
- * To free the structure constructed by this function, free the first element and free the dynar:
- *
- * free(xbt_dynar_get_ptr(dynar,0));
- * xbt_dynar_free(&dynar);
+ * Actually this function puts a bunch of \0 in the memory area you passed as
+ * argument to separate the elements, and pushes the address of each chunk
+ * in the resulting dynar. Yes, that's uneven. Yes, that's gory. But that's efficient.

-/** @brief Get a single line from the stream (reimplementation of the GNU getline)
- *
- * This is a redefinition of the GNU getline function, used on platforms where it does not exists.
- *
- * 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.
