dlfindn - get nth logical RMSfile description
LF *dlfindn (dbname, n)
Dlfindn searches the C/Base database catalog for the nth logical RMSfile defined in the given database. If found, a pointer to a structure describing the logical RMSfile is returned. If the given database contains fewer than n entries, a NULL pointer is returned and the RMS error message is set describing the reason for not finding the logical RMSfile entry.
Dbname is the name of the database. If dbname is a NULL pointer or an empty string, the default database name is used.
The order of logical RMSfiles within a database is undefined and can change at any time. This function is designed for scanning all logical RMSfiles defined for one database; not looking for one particular entry.
The structure returned by dlfindn is defined in the include file <cbase/dbase.h>.
A value of NULL is returned if there are fewer than n logical RMSfiles defined for the given database.
The returned value points to static data whose contents are overwritten with every call.
