A message domain is a set of translatable <i>msgid</i> |
| 53 |
messages. Usually, every software package has its own |
| 54 |
message domain. The domain name is used to determine the |
| 55 |
message catalog where a translation is looked up; it must be |
| 56 |
a non-empty string.</td></table> |

<td width="10%"></td><td width="90%"> |
| 62 |
The current message domain is used by the <b>gettext</b>, |
| 63 |
<b>ngettext</b> functions, and by the <b>dgettext</b>, |
| 64 |
<b>dcgettext</b>, <b>dngettext</b> and <b>dcngettext</b> |

functions when called with a NULL domainname |
| 66 |

If <i>domainname</i> is not NULL, the current message domain |
| 73 |
is set to <i>domainname</i>. The string the function stores |

If successful, the <b>textdomain</b> function returns the |
| 91 |
current message domain, after possibly changing it. The |
| 92 |
resulting string is valid until the next <b>textdomain</b> |
| 93 |
call and must not be modified or freed. If a memory |
| 94 |
allocation failure occurs, it sets <b>errno</b> to |
| 95 |
<b>ENOMEM</b> and returns NULL.</td></table> |
