<p>For consistent behavior you'll probably want to use ALLOC to ensure the caller owns the data, but MINMEM is useful for avoiding extra copy of data when you are sure the header wont go away. Most of the time you'll probably want EXT too, but note that extensions tags don't generally honor the other flags, MINMEM, RAW, ALLOC and ARGV are only relevant for non-extension data. </p>

<p>Type-safe methods for inserting tag data to header. </p>
<p>Tag data type is validated to match the function type, ie things like headerPutUint32(h, RPMTAG_NAME, ...) will return failure. For non-array types size must equal 1, and data is checked to be non-NULL. For array types, add-or-append mode is always used.</p>
<p><a class="el" href="group__header.html#ga9a7cc53243734db48200933aecaea57c">headerPutString()</a> can be used on both RPM_STRING_TYPE and RPM_STRING_ARRAY_TYPE (to add a single string into the array) tags, for others the type must match exactly.</p>
