[Libsysio-commit] RedStorm: libsysio/dev/stdfd stdfd.c

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio/dev/stdfd
In directory sc8-pr-cvs1:/tmp/cvs-serv5485/dev/stdfd

Modified Files:
      Tag: RedStorm
	stdfd.c 
Log Message:


Integrate RedStorm_merge branch. This incorporates changes required
for the Red Storm cnos.

Some things didn't make it:
a) The mount call change. We *really* want the original libsysio
	version. Special, libsysio only, flags are unavailable without it.
	Semantic differences are possible without it.
b) The Red Storm specific startup and initial mounts source. These
	should be moved into the Cray-specific C library -- With
	startup.c?

One thing enhanced; The native driver doio routine from RedStorm_merge err'd
	if an iovec was more than one entry long. This will break things
	in the future. Added code, in doio, to loop over iovecs, calling
	the low-level transfer function (pread) for each element.

Notes:

The typedef and defined failure value for ioid_t need to be placed
in a more accessible place for the Cray. User-level source should *not*
include sysio.h ever.

The async IO call prototypes (those that begin with an `i') should be
prototyped somewhere outside libsysio. Look at ASCI Red in order to
promote backward compatibility?

The mount prototype in the catamount `C' lib includes should be altered
to reflect ours.

Prototypes for _sysio_start() and _sysio_shutdown() should be available
externally for startup.c. It, too, shouldn't include sysio.h.
