int putann(DB_Annotator an, DB_Annotation *annot)
Return:
This function writes the next annotation for the output annotator specified by
an from the annotation structure pointed to by annot. Output
annotators are numbered 0, 1, 2, etc. The caller must fill in all fields of
the annotation structure. Using version 9.7 and later versions of the DB
library, annotations may be written in any order (see section Annotation Order).
Earlier versions require that annotations be supplied to putann in
canonical order, and return an error code of -3 if an out-of-order
annotation is supplied. All programs that write signals or annotations
must invoke dbquit to close the output files properly
(see section dbquit).
Several of the example programs in chapter 6 illustrate the use of
putann; for example, see section Example 1: An Annotation Filter.
