These four chunks are included in the definition of every "EA IFF 85" file. All are text chunks; their data portion consists solely of text. Each of these chunks is optional.
typedef struct {
#define NameID 'NAME' /* ckID for Name Chunk. */
#define AuthorID 'AUTH' /* ckID for Author Chunk. */
#define CopyrightID '(c) ' /* ckID for Copyright Chunk. */
#define AnnotationID 'ANNO' /* ckID for Annotation Chunk. */
} TextChunk;
ckID is either ' NAME', ' AUTH', '(c) ', or ' ANNO', depending on whether the chunk as a Name Chunk, Author Chunk, Copyright Chunk, or Annotation Chunk, respectively. For the Copyright Chunk, the 'c' is lowercase and there is a space (0x20) after the close parenthesis.
ckSize is the size of the data portion of the chunk, in this case the text.
text contains pure ASCII characters. It is not a pstring nor a C string. The number of characters in text is determined by ckSize. The contents of text depend on the chunk, as described below:
Name Chunk
text contains the name of the sampled sound. The Name Chunk is optional. No more than one Name Chunk may exist within a FORM AIFF.
Author Chunk
text contains one or more author names. An author in this case is the creator of a sampled sound. The Author Chunk is optional. No more than one Author Chunk may exist within a FORM AIFF.
Copyright Chunk
The Copyright Chunk contains a copyright notice for the sound. text contains a date followed by the copyright owner. The chunk ID '(c) ' serves as the copyright characters '©'. For example, a Copyright Chunk containing the text "1988 Apple Computer, Inc." means "© 1988 Apple Computer, Inc."
The Copyright Chunk is optional. No more than one Copyright Chunk may exist within a FORM AIFF.
Annotation Chunk
text contains a comment. Use of this chunk is discouraged within FORM AIFF. The more powerful Comments Chunk should be used instead. The Annotation Chunk is optional. Many Annotation Chunks may exist within a FORM AIFF.
