Truxton exif create

This creates an Exchangeable image file format object. You can use this to add records to the [EXIF] table in the database.

Syntax

uint64_t truxton_exif_create( uint64_t truxton_handle );

Parameters

truxton_handle

The Truxton instance this event will belong. This handle comes from calling truxton_create().

Return value

A handle to an EXIF object.
