// writedatasetfile.C
// ==================
//
// reads the dataset information from the database and writes it into a
// txt file
//
// Usage:
//  .x writedatasetfile.C+(dsno, "dspath")
//
// Make sure, that database and password are corretly set in a resource
// file called sql.rc and the resource file is found.
//
// Returns 2 in case of failure, 1 in case of success and 0 if the connection
// to the database is not working.
