Syntax

DINFO(directory-id, info-item)

directory-id: specifies the identifier that was assigned when the directory was opened, generally by the DOPEN function.
info-item: specifies the information item to be retrieved. DINFO returns a blank if the value of info-item is invalid.

Details

Directories that are opened with the DOPEN function are identified by a directory-id. Use DOPTNAME to determine the names of the available system-dependent directory information items. Use DOPTNUM to determine the number of directory information items available.

Under Windows, the only info-item that is available is Directory, which is the pathname of directory-id. If directory-id points to a list of concatenated directories, then Directory is the list of concatenated directory names.

Example of Obtaining Directory Information

data a;
  rc=filename("tmpdir", "c:");
  put "rc = 0 if the directory exists: " rc=;
  did=dopen("tmpdir");
  put did=;
  numopts=doptnum(did);
  put numopts=;
  do i = 1 to numopts;
    optname = doptname(did,i);
    put i= optname=;
    optval=dinfo(did,optname);
    put optval=;
  end;
run;
