#define G3D_IFF_MKID(a,b,c,d)
Generate an IFF chunk identifier from character representation, e.g. G3D_IFF_MKID('F','O','R','M').
gboolean g3d_iff_check (G3DStream *stream,guint32 *id,gsize *len);
Checks a stream for a valid IFF signature and reads the top level container.
gsize g3d_iff_read_chunk (G3DStream *stream,guint32 *id,gsize *len,guint32 flags);
Reads one chunk header from an IFF file.
gpointer g3d_iff_handle_chunk (G3DIffGlobal *global,G3DIffLocal *plocal,G3DIffChunkInfo *chunks,guint32 flags);
Handle an IFF chunk based on chunk description.
gboolean g3d_iff_chunk_matches (guint32 id,gchar *tid);
Check whether id
and tid
match.
gboolean g3d_iff_read_ctnr (G3DIffGlobal *global,G3DIffLocal *local,G3DIffChunkInfo *chunks,guint32 flags);
Read subchunks in current chunk and handle them appropriately.
gchar *
g3d_iff_id_to_text (guint32 id);
Get the text representation of an IFF chunk identifier.
FILE * g3d_iff_open (const gchar *filename,guint32 *id,guint32 *len);
Opens an IFF file, checks it and reads its top level container.
int g3d_iff_readchunk (FILE *f,guint32 *id,guint32 *len,guint32 flags);
Reads one chunk header from an IFF file.
gboolean (*G3DIffChunkCallback) (G3DIffGlobal *global,G3DIffLocal *local);
IFF callback function prototype.
#define G3D_IFF_SUBCHUNK_LEN16 0x10
All chunks except the toplevel ones have 16-bit sizes.
#define g3d_iff_chunk_callback G3DIffChunkCallback
IFF chunk callback (deprecated).
