SYNOPSIS
#include
DICT *dtopen (filename, mode)
char *filename;
char *mode;
DESCRIPTION
Dtopen opens the RMS dictionary file for the RMSfile filename for
reading (mode is "r"). Filename points to a string of ASCII
characters representing the logical name or a pathname of the
RMSfile, terminated by a null character. See cdict(C-1) for
creating data dictionaries.
The pointer returned should be saved and used on subsequent calls
to dtaccess(C-3), dtefld(C-3), dtefldn(C-3), dtfind(C-3),
dtfindn(C-3), dtfindi(C-3), dtfindk(C-3), and dtclose(C-3).
