-/** @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.
- *
- * xbt_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 xbt_getline() will allocate a buffer for storing the
- * line, which should be freed by the user program.
- *
- * Alternatively, before calling xbt_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, xbt_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.
