dbinit

int dbinit(char *record, DB_Anninfo *aiarray, unsigned int nann,
           DB_Siginfo *siarray, unsigned int nsig)

Return:

>0

Success: the returned value is the number of input signals (i.e., the number of valid entries in siarray)

0

Annotation files opened successfully, input signals unavailable (not an error for programs that don't need them; no error message is printed if nsig is 0)

-1

Failure: unable to read `header' file (probably incorrect record name)

-2

Failure: incorrect `header' file format

-3

Failure: unable to open input annotation file

-4

Failure: unable to open output annotation file

-5

Failure: illegal stat (in aiarray) specified for annotation file (see section Annotator Information Structures)

This function opens database files other than output signal files for a selected record. The code

n = dbinit(record, a, na, s, ns);

is exactly equivalent to

n = annopen(record, a, na);
if (n == 0)
    n = isigopen(record, s, ns);

See section Example 9: A Signal Averager, for an illustration of the use of dbinit. See section osigopen, and see section osigfopen, for methods of opening output signal files.
