dbfindn - get nth database description
#include Dbfindn searches the C/Base database catalog for the nth database description.
If found, dbfindn returns a pointer to a structure describing the database.
If the C/Base database catalog contains fewer than n entries, dbfindn returns
a NULL pointer and sets the RMS error message to a description of the reason
for not finding the database entry. The order of database entries in the C/Base
database catalog is undefined and can change at any time. This function is designed
for scanning all database entries, not looking for one particular entry. The
structure returned by dbfindn is defined in the include file dbfind(C-3), dbopen(C-3)
DIAGNOSTICS A value of NULL is returned if there are fewer than n entries in
the C/Base database catalog.
