header.c File Reference

Add locale specific tag to header. A NULL lang is interpreted as the C locale. Here are the rules:

 *      - If the tag isn't in the header, it's added with the passed string
 *         as new value.
 *      - If the tag occurs multiple times in entry, which tag is affected
 *         by the operation is undefined.
 *      - If the tag is in the header w/ this language, the entry is
 *         *replaced* (like headerModifyEntry()).
