[Libsysio-commit] HEAD: libsysio/drivers/native fs_native.c

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

Update of /cvsroot/libsysio/libsysio/drivers/native
In directory sfp-cvsdas-2.v30.ch3.sourceforge.com:/tmp/cvs-serv2260/drivers/native

Modified Files:
	fs_native.c 
Log Message:


Added ifsync and ifdatasync. These are asynchronous versions of the standard
calls. In fact, the core has been reworked so that the async versions are
the core implementation.

For backward compatibility, if your driver has old versions you may set the
new inop_isync ad inop_idatasync fields to NULL and retain the old interface
and, synchronous, semantics. The existing fields were renamed to
inop_old_sync and inop_old_datasync and will be deprecated in the future.

One important, related, change is that the ioctx record has a new field, called
ioctx_args, which is a void * type. It's only used to pass the real function to call aby the code that is faking the async API but using the old fsync and
fdatasync.
