dba_popen() establishes a
persistent database instance for
path with mode
using handler.
path is commonly a
regular path in your filesystem.
mode is "r" for read
access, "w" for read/write access to an already existing
database, "c" for read/write access and database creation if
it doesn't currently exist, and "n" for create, truncate and
read/write access.
handler is the name of the handler
which shall be used for accessing
path. It is passed all optional parameters given to
dba_popen() and can act on behalf of
them.
dba_popen() returns a positive
handle or FALSE, in the case
the open is successful or fails, respectively.
