Chris@1 9 <small>
Chris@1 10 [<a class="el" href="group__flac__metadata.html">FLAC/metadata.h: metadata interfaces</a>]</small>
Chris@1 11 </h1><hr><a name="_details"></a><h2>Detailed Description</h2>
Chris@1 12 The level 1 interface provides read-write access to FLAC file metadata and operates directly on the FLAC file.
Chris@1 13 <p>
Chris@1 14 The general usage of this interface is:<p>
Chris@1 15 <ul>
Chris@1 16 <li>Create an iterator using <a class="el" href="group__flac__metadata__level1.html#ga2">FLAC__metadata_simple_iterator_new()</a></li><li>Attach it to a file using <a class="el" href="group__flac__metadata__level1.html#ga5">FLAC__metadata_simple_iterator_init()</a> and check the exit code. Call <a class="el" href="group__flac__metadata__level1.html#ga6">FLAC__metadata_simple_iterator_is_writable()</a> to see if the file is writable, or only read access is allowed.</li><li>Use <a class="el" href="group__flac__metadata__level1.html#ga7">FLAC__metadata_simple_iterator_next()</a> and <a class="el" href="group__flac__metadata__level1.html#ga8">FLAC__metadata_simple_iterator_prev()</a> to traverse the blocks. This is does not read the actual blocks themselves. <a class="el" href="group__flac__metadata__level1.html#ga7">FLAC__metadata_simple_iterator_next()</a> is relatively fast. <a class="el" href="group__flac__metadata__level1.html#ga8">FLAC__metadata_simple_iterator_prev()</a> is slower since it needs to search forward from the front of the file.</li><li>Use <a class="el" href="group__flac__metadata__level1.html#ga11">FLAC__metadata_simple_iterator_get_block_type()</a> or <a class="el" href="group__flac__metadata__level1.html#ga14">FLAC__metadata_simple_iterator_get_block()</a> to access the actual data at the current iterator position. The returned object is yours to modify and free.</li><li>Use <a class="el" href="group__flac__metadata__level1.html#ga15">FLAC__metadata_simple_iterator_set_block()</a> to write a modified block back. You must have write permission to the original file. Make sure to read the whole comment to <a class="el" href="group__flac__metadata__level1.html#ga15">FLAC__metadata_simple_iterator_set_block()</a> below.</li><li>Use <a class="el" href="group__flac__metadata__level1.html#ga16">FLAC__metadata_simple_iterator_insert_block_after()</a> to add new blocks. Use the object creation functions from <a class="el" href="group__flac__metadata__object.html">here </a> to generate new objects.</li><li>Use <a class="el" href="group__flac__metadata__level1.html#ga17">FLAC__metadata_simple_iterator_delete_block()</a> to remove the block currently referred to by the iterator, or replace it with padding.</li><li>Destroy the iterator with <a class="el" href="group__flac__metadata__level1.html#ga3">FLAC__metadata_simple_iterator_delete()</a> when finished.</li></ul>
Chris@1 17 <p>
Chris@1 18 <dl compact><dt><b>Note:</b></dt><dd>The FLAC file remains open the whole time between <a class="el" href="group__flac__metadata__level1.html#ga5">FLAC__metadata_simple_iterator_init()</a> and <a class="el" href="group__flac__metadata__level1.html#ga3">FLAC__metadata_simple_iterator_delete()</a>, so make sure you are not altering the file during this time.<p>
Chris@1 19 Do not modify the <em>is_last</em>, <em>length</em>, or <em>type</em> fields of returned <a class="el" href="structFLAC____StreamMetadata.html">FLAC__StreamMetadata</a> objects. These are managed automatically.<p>
Chris@1 20 If any of the modification functions (<a class="el" href="group__flac__metadata__level1.html#ga15">FLAC__metadata_simple_iterator_set_block()</a>, <a class="el" href="group__flac__metadata__level1.html#ga17">FLAC__metadata_simple_iterator_delete_block()</a>, <a class="el" href="group__flac__metadata__level1.html#ga16">FLAC__metadata_simple_iterator_insert_block_after()</a>, etc.) return <code>false</code>, you should delete the iterator as it may no longer be valid. </dd></dl>

Chris@1 764 Write a block back to the FLAC file. This function tries to be as efficient as possible; how the block is actually written is shown by the following:<p>
Chris@1 765 Existing block is a STREAMINFO block and the new block is a STREAMINFO block: the new block is written in place. Make sure you know what you're doing when changing the values of a STREAMINFO block.<p>
Chris@1 766 Existing block is a STREAMINFO block and the new block is a not a STREAMINFO block: this is an error since the first block must be a STREAMINFO block. Returns <code>false</code> without altering the file.<p>
Chris@1 767 Existing block is not a STREAMINFO block and the new block is a STREAMINFO block: this is an error since there may be only one STREAMINFO block. Returns <code>false</code> without altering the file.<p>
Chris@1 768 Existing block and new block are the same length: the existing block will be replaced by the new block, written in place.<p>
Chris@1 769 Existing block is longer than new block: if use_padding is <code>true</code>, the existing block will be overwritten in place with the new block followed by a PADDING block, if possible, to make the total size the same as the existing block. Remember that a padding block requires at least four bytes so if the difference in size between the new block and existing block is less than that, the entire file will have to be rewritten, using the new block's exact size. If use_padding is <code>false</code>, the entire file will be rewritten, replacing the existing block by the new block.<p>
Chris@1 770 Existing block is shorter than new block: if use_padding is <code>true</code>, the function will try and expand the new block into the following PADDING block, if it exists and doing so won't shrink the PADDING block to less than 4 bytes. If there is no following PADDING block, or it will shrink to less than 4 bytes, or use_padding is <code>false</code>, the entire file is rewritten, replacing the existing block with the new block. Note that in this case any following PADDING block is preserved as is.<p>
Chris@1 771 After writing the block, the iterator will remain in the same place, i.e. pointing to the new block.<p>
