#### Procedure

       void dasopr_c ( ConstSpiceChar  * fname,
                       SpiceInt        * handle )

#### Abstract

       Open a DAS file for reading.

#### Required_Reading

       DAS

#### Keywords

       DAS
       FILES

#### Brief_I/O

       Variable  I/O  Description
       --------  ---  --------------------------------------------------
       fname      I   Name of a DAS file to be opened.
       handle     O   Handle assigned to the opened DAS file.

#### Detailed_Input

       fname       is the name of a DAS file to be opened with read
                   access.

#### Detailed_Output

       handle      is the handle that is  associated with the file. This
                   handle is used to identify the file in subsequent
                   calls to other DAS routines.

#### Parameters

       None.

#### Exceptions

       1) If the input filename is blank, the error SPICE(BLANKFILENAME)
          will be signaled.

       2) If the specified file does not exist, the error
          SPICE(FILENOTFOUND) will be signaled.

       3) If the specified file has already been opened for read
          access, the handle already associated with the file is
          returned.

       4) If the specified file has already been opened for write
          access, the error SPICE(DASRWCONFLICT) is signaled.

       5) If the specified file has already been opened by a non-DAS
          routine, the error SPICE(DASIMPROPOPEN) is signaled.

       6) If the specified file cannot be opened without exceeding
          the maximum allowed number of open DAS files, the error
          SPICE(DASFTFULL) is signaled.

       7) If the named file cannot be opened properly, the error
          SPICE(DASOPENFAIL) is signaled.

       8) If the file record cannot be read, the error
          SPICE(FILEREADFAILED) will be signaled.

       9) If the specified file is not a DAS file, as indicated by the
          file's ID word, the error SPICE(NOTADASFILE) is signaled.

      10) If no logical units are available, the error will be
          signaled by routines called by this routine.

#### Files

       See argument `fname'.

#### Particulars

       Most DAS files require only read access. If you do not need to
       change the contents of a file, you should open it using dasopr_c.

#### Examples

       1)  Open the existing DAS file TEST.DAS for reading.

              dasopr_c ( "TEST.DAS", &handle );

#### Restrictions

       None.

#### Literature_References

       None.
