Created page with "This saves the data to the <code><nowiki>[</nowiki>EXIF<nowiki>]</nowiki></code> table in the database. =Syntax= <source lang="C"> void truxton_exif_save( uint..."

New page

This saves the data to the <code><nowiki>[</nowiki>[[EXIF Table|EXIF]]<nowiki>]</nowiki></code> table in the database.
