dbfile

char *dbfile(char *type, char *record)

Return:

(char *)

pointer to a filename, or NULL

This function attempts to locate an existing DB file by searching the database path (see section The Database Path). Normally, the file is specified by its type (e.g., `header', or an annotator name such as `atruth') and by the record to which it belongs. A file that does not include a record name as part of its name can be found by dbfile if the name is passed in the type variable and record is NULL. The string returned by dbfile includes the appropriate component of the database path; since the database path may include empty or non-absolute components, the string is not necessarily an absolute pathname. If the file cannot be found, dbfile returns NULL. (This function was first introduced in DB library version 4.3.)
