DESC3() and desc3c()

Fortran version:

        CHARACTER*(*), INTENT(IN   ) :: FNAME   !  file name for query

C version:

desc3c() is a C wrapper calling the Fortran DESC3()

    int desc3c( const char    * fname,
                IOAPI_Bdesc3  * bdesc ,
                IOAPI_Cdesc3  * cdesc ) ;


DESC3() puts the description of the file with logical name FNAME into file description commons found in include file FDESC3.EXT ; desc3c() returns the file description in the structs at arguments "bdesc" and "cdesc" (defined in fdesc3.h ). Returns .TRUE. or 1, respectively, on success, and .FALSE. or 0 on failure.

If FNAME is invalid, writes an error message indicating the nature of the problem to the log and returns a .FALSE. (or 0).


USE M3UTILIO or INCLUDE 'IODECL3.EXT' and INCLUDE 'FDESC3.EXT' for Fortran, or #include "iodecl3.h" and #include "fdesc3.h" for C.

FNAME must have length at most 16.

FNAME must already have been opened by OPEN3() or open3c() (and the I/O API must have been initialized with INIT3() or init3c() ).

The following *ATT*() routines deal with reading and writing attributes (possibly in addition to the standard ones) to or from netCDF-based I/O API files:

Fortran Usage:

See sample programs M3CPLE, PRESZ, and VERTINTEGRAL for additional usage examples.
    IF ( DESC3( 'MYFILE' ) ) THEN
        !!  Commons BDESC, CDESC from INCLUDE-file FDESC3.EXT
        !!  contain description of the file with logical name MYFILE.
    END IF

C Usage:

    #include "iodecl3.h"
    if ( desc3c( "MYFILE", bdesc, cdesc ) )
            /*  Structs *bdesc and *cdesc contain description
                of the file with logical name MYFILE.  */
