NAME

pvm_archcode - Returns the data representation code for aPVM 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 routinepvm_archcodereturns 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 differentsizes).This lets you know when you can get away with using PvmDataRawinstead of PvmDataDefaultencoding 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 thatif two different arch names map to the same value then they're compatible.

EXAMPLES

C:        struct pvmhostinfo *hip;        int i;        pvm_config((int *)0, (int *)0, &hip);        i = pvm_archcode(hip[0].hi_arch);Fortran:        CALL PVMFARCHCODE( 'RS6K', k )

ERRORS

No error conditions are be returned by pvm_archcode.
