Created page with "This creates an [https://en.wikipedia.org/wiki/Exif Exchangeable image file format] object. This corresponds to the <code>[ID]</code> column of the <code><nowiki>[</nowiki>E..."
New page
This creates an [https://en.wikipedia.org/wiki/Exif Exchangeable image file format] object.

This corresponds to the <code>[ID]</code> column of the <code><nowiki>[</nowiki>[[EXIF Table|EXIF]]<nowiki>]</nowiki></code> table in the database.



=Syntax=

<source lang="C">

void truxton_exif_get_id( uint64_t exif_handle, char * destination_string, size_t max_size );

</source>



=Parameters=

==<code>exif_handle</code>==

This handle comes from calling <code>[[truxton_exif_create]]()</code> or <code>[[truxton_file_create_exif]]()</code>.



==<code>destination_string</code>==

The string to be written to. 



==<code>max_size</code>==

The maximum number of characters that can be written to <code>destination_string</code>.
