Description
Open an existing paradox database file. The actual file has to
be opened before with fopen(). The first parameter
is the return value of px_new(). This function can
also be used to open primary index files and tread them like a paradox
database. This is supported for those who would like to investigate
a primary index. It cannot be used to accelerate access to a database
file. Returns FALSE on failure.
