WdmEnt: Library for WDM Access
The purpose of this library is to provide a 64-bit compatible DLL for communication between an external program and WDM files. The DLL includes the entry points described below. Source code for the DLL is available here: https://github.com/respec/FORTRAN/tree/master/f90apps/WdmEnt
Test sequences are being developed for exercising all the entry points of the DLL from a dotNet application as well as from a Fortran program. For dotNet testing code, see https://github.com/respec/FORTRAN/tree/master/vbDrivers/WdmEntDriverVB. For Fortran testing code, see https://github.com/respec/FORTRAN/tree/master/f90apps/WdmEntDriverFortran.
F90_MSG (atcWDM) calls LOG_MSG, has entry point
F90_W99OPN (atcWDM) open unit 99 for writing messages
F90_W99CLO (atcWDM) close unit 99 for writing messages
F90_WDMOPN (IHM) given a wdm file name and a unit number, open it if it isn't already open
F90_WDMCLO (IHM) close a wdm file with a fortran close statement, mark records in buffer as not usable
F90_WDBOPN (IHM) given a wdm file name and a read-only flag, open the wdm file
F90_WDBOPNR (atcWDM) subroutine version of above, returns wdm file unit number and a retcod
F90_WDFLCL (atcWDM) close a wdm file using wdm code to remove it from the wdm buffer
F90_INQNAM (atcWDM) check to see if a file name is open
F90_WDDSNX (atcWDM) search for the next data set greater than or equal to dsn
F90_WDCKDT (atcWDM) check data set for existance and type
F90_WDTGET (atcWDM) get timeseries information from wdm file
F90_WDTPUT (IHM, atcWDM) put timeseries data into a wdm file
F90_WTFNDT (atcWDM) determine starting and ending dates of data in data set
F90_WDBSGC (atcWDM) get value of character search attribute for a dsn
F90_WDBSGI (IHM, atcWDM) get value of integer search attribute for a dsn
F90_WDBSGR (atcWDM) get value of real search attribute for a dsn
F90_WDBSAC (atcWDM) adds (or modifies) character search attribute on given dsn
F90_WDBSAI (atcWDM) adds (or modifies) integer search attribute on given dsn
F90_WDBSAR (atcWDM) adds (or modifies) real search attribute on given dsn
F90_WDLBAX (atcWDM) add a new data-set label, but no search attributes or data, sets pointers
F90_WDDSDL (atcWDM) delete a data set from the WDMSFL with no user interaction
F90_WDSAGY (atcWDM) gets general detail information about specified attribute
F90_GETATT (atcWDM) calls wdgtat to retrieve search attributes by position in label
LOG_MSG write message to error.fil
INQUIRE_NAME given a file name, return its unit number if it is open, else return first available unit number
GET_WDM_FUN given a file unit number, return this one if it isn't in use, else the next available
