Add tag to header. Duplicate tags are okay, but only defined for iteration (with the exceptions noted below). While you are allowed to add i18n string arrays through this function, you probably don't mean to. See headerAddI18NString() instead.
Parameters:
Returns: 1 on success, 0 on failure
Definition at line 497 of file header.h.
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()). *
Parameters:
Returns: 1 on success, 0 on failure
Definition at line 553 of file header.h.
Add or append element to tag array in header.
Todo: Arg 'p' should have const.
Parameters:
Returns: 1 on success, 0 on failure

Swap int_32 and int_16 arrays within header region.
This code is way more twisty than I would like.
A bug with RPM_I18NSTRING_TYPE in rpm-2.5.x (fixed in August 1998) causes the offset and length of elements in a header region to disagree regarding the total length of the region data.
The 'fix' is to compute the size using both offset and length and return the larger of the two numbers as the size of the region. Kinda like computing left and right Riemann sums of the data elements to determine the size of a data structure, go figger :-).
There's one other twist if a header region tag is in the set to be swabbed, as the data for a header region is located after all other tag data.
Parameters:
Returns: no. bytes of data in region, -1 on error
