NAME

       pvm_archcode - Returns the data representation code for a PVM architecture name.

SYNOPSIS

       C    int cod = pvm_archcode( char *arch )

       Fortran   call pvmfarchcode( arch, cod )

PARAMETERS

       arch    Character string containing the architecture name.

       cod     Integer returning architecture code.

DESCRIPTION

       The routine pvm_archcode returns an integer given an architecture name.  The code returned
       identifies machines with compatible binary data formats.  For example, SUN4 and RS6K  have
       the  same  code,  while  ALPHA has a different one (because a few datatypes have different
       sizes).  This lets you know when you  can  get  away  with  using  PvmDataRaw  instead  of
       PvmDataDefault encoding to pass messages between tasks on two machines.

       Naturally,  you  shouldn't assume the values returned by pvm_archcode are etched in stone;
       the numbers have no intrinsic meaning except that if two different arch names map  to  the
       same value then they're compatible.

       This  routine  is  actually obsolete in the sense that the architecture codes returned are
       already  available  in  the  hi_dsig  field  of  the  pvmhostinfo  structure  returned  by
       pvm_config(),  as  shown  in  the  below example.  The routine is maintained for backwards
       compatibility only.

EXAMPLES

       C:
            struct pvmhostinfo *hip;
            int i;

            pvm_config((int *)0, (int *)0, &hip);
            i = pvm_archcode(hip[0].hi_arch);

            /* or you could just do:  i = hip[0].hi_dsig;  */

       Fortran:
            CALL PVMFARCHCODE( 'RS6K', k )

ERRORS

       On success, pvm_archcode returns a positive integer data signature.

       The following error conditions can be returned as well:

       PvmBadParam
              giving an invalid architecture name.

       PvmNotFound
              there is no host with the given architecture name in the  current  virtual  machine
              configuration.

       PvmSysErr
              pvmd not responding.
