GsfBlob* gsf_blob_new (gsize size, gconstpointer data_to_copy, GError **error);
Creates a new GsfBlob object to hold the specified data. The blob can then be used as a facility for reference-counting for the data. The data is copied internally, so the blob does not hold references to external chunks of memory.
| size: | Size of the data in bytes. | 
| data_to_copy: | Data which will be copied into the blob, or NULLifsizeis zero. | 
| error: | location to store error, or NULL. | 
| Returns : | A newly-created GsfBlob, or NULLif the data could not be copied.
Error domain: GSF_ERROR
Possible errors: GSF_ERROR_OUT_OF_MEMORY if thedata_to_copycould not be copied. | 
gsize gsf_blob_get_size (GsfBlob *blob);
Queries the size in bytes of the data stored in the blob.
| blob: | A GsfBlob. | 
| Returns : | Size in bytes, or 0 if the data is NULL. | 
gconstpointer gsf_blob_peek_data (GsfBlob *blob);
Queries a pointer to the data stored in the blob. This does not copy the data for you; it returns a pointer to the actual buffer which the blob uses internally, so you should not free this buffer on your own.
| blob: | A GsfBlob. | 
| Returns : | Pointer to the data stored in the blob, or NULLif the size
of the data is zero. | 
gboolean gsf_structured_blob_write (GsfStructuredBlob *blob, GsfOutfile *container);
Dumps structured blob blob onto the container.  Will fail if the output is
not an Outfile and blob has multiple streams.
| blob: | |
| container: | |
| Returns : | TRUE on success. | 
GsfStructuredBlob* gsf_structured_blob_read (GsfInput *input);
| input: | An input (potentially a GsfInfile) holding the blob | 
| Returns : | a freshly created tree of blobs |
