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.
