| The integral datatypes used in the system calls are <code>int</code>, |
| <code>unsigned int</code>, <code>long</code>, <code>unsigned long</code>, |
| <code>mode_t</code>, and <code>time_t</code>. |
| |
| <p><code>int</code>, <code>unsigned int</code>, <code>mode_t</code> and <code>time_t</code> are |
| implemented as 32 bit values in this protocol. |
| |
| <p><code>long</code> and <code>unsigned long</code> are implemented as 64 bit types. |
| |
| <p>See <a href="Limits.html#Limits">Limits</a>, for corresponding MIN and MAX values (similar to those |
| in <samp><span class="file">limits.h</span></samp>) to allow range checking on host and target. |
| |
| <p><code>time_t</code> datatypes are defined as seconds since the Epoch. |
| |
| <p>All integral datatypes transferred as part of a memory read or write of a |
| structured datatype e.g. a <code>struct stat</code> have to be given in big endian |
| byte order. |
