ARCHCODE(3PVM)						       ARCHCODE(3PVM)

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.

DISCUSSION
  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.

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.
