/*      VARIABLE  I/O  DESCRIPTION */
/*      --------  ---  -------------------------------------------------- */
/*      FILE       I   The name of a file to be examined. */
/*      ARCH       O   The architecture of the kernel file. */
/*      TYPE       O   The type of the kernel file. */
/*      NUMBER     O   The logical unit number for the open file FILE. */

/* $ Detailed_Input */

/*     FILE        is the name of a SPICE kernel file whose architecture */
/*                 and type are desired. This file must be closed when */
/*                 this routine is called. */

/* $ Detailed_Output */

/*     ARCH        is the file architecture of the SPICE kernel file */
/*                 specified be FILE. If the architecture cannot be */
/*                 determined or is not recognized the value '?' is */
/*                 returned. */

/*                 Architectures currently recognized are: */

/*                    DAF - The file is based on the DAF architecture. */
/*                    DAS - The file is based on the DAS architecture. */
/*                    XFR - The file is in a SPICE transfer file format. */
/*                    DEC - The file is an old SPICE decimal text file. */
/*                    ASC -- An ASCII text file. */
/*                    KPL -- Kernel Pool File (i.e., a text kernel) */
/*                    TXT -- An ASCII text file. */
/*                    TE1 -- Text E-Kernel type 1. */
/*                     ?  - The architecture could not be determined. */

/*                 This variable must be at least 3 characters long. */

/*     TYPE        is the type of the SPICE kernel file. If the type */
/*                 can not be determined the value '?' is returned. */

/*                 Kernel file types may be any sequence of at most four */
/*                 printing characters. NAIF has reserved for its use */
/*                 types which contain all upper case letters. */

/*                 A file type of 'PRE' means that the file is a */
/*                 pre-release file. */

/*                 This variable may be at most 4 characters long. */

/*     NUMBER      The logical unit number assigned to the file FILE */
/*                 when opened.  An integer, returned to the calling */
/*                 routine. */

/* $ Parameters */

/*     RECL        is the record length of a binary kernel file. Each */
/*                 record must be large enough to hold 128 double */
/*                 precision numbers. The units in which the record */
/*                 length must be specified vary from environment to */
/*                 environment. For example, VAX Fortran requires */
/*                 record lengths to be specified in longwords, */
/*                 where two longwords equal one double precision */
/*                 number. */

/* $ Exceptions */

/*      1)  If the inquire on the filename specified by FILE fails for */
/*          some reason, the error SPICE(INQUIREERROR) will be signaled. */

/*      2)  If the file specified by FILE is already open, the error */
/*          SPICE(FILECURRENTLYOPEN) will be signaled. */

/*      3)  If the file specified by FILE does not exist, the error */
/*          SPICE(NOSUCHFILE) will be signaled. */

/*      4)  If the attempt to open the file specified by FILE fails, the */
/*          error SPICE(FILEOPENFAILED) will be signaled. */

/*      5)  If all attempts to open the file specified by FILE fail, the */
/*          error SPICE(FILEOPENFAILED) will be signaled. */

/*      6)  If all attempts to read from the file specified be FILE */
/*          fail, the error SPICE(FILEREADFAILED) will be signaled. */

/* $ Files */

/*     The SPICE kernel file specified by FILE is opened and then */
/*     closed by this routine to determine its file architecture and */
/*     type. Names of open files should not be passed to this routine. */

/* $ Particulars */

/*     This subroutine is a support utility routine that determines the */
/*     architecture and type of a SPICE kernel file. */

/* $ Examples */

/*     None. */

/* $ Restrictions */

/*     This routine should only be called as part of spacit or tobin */
/*     by spat2b. */
