[Libsysio-commit] HEAD: libsysio/include creds.h

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

Update of /cvsroot/libsysio/libsysio/include
In directory ddv4jf1.ch3.sourceforge.com:/tmp/cvs-serv29952/include

Modified Files:
	creds.h 
Log Message:


Modified to allow the package user to specify alternate routines for
the acquisition of credentials and implementation of permission check policy.

In order to arrange the acquisition of alternate credentials, the
pointers to _sysio_get_credentials and _sysio_put_credentials should be
overwritten.

Your get_credentials routine should set the passed pointer to a
credentials structure with the uid and gids set with the real
values, if the formal called 'effective', is zero or the effective values
if non-zero.

Your put_credentials routine is called when the core no longer requires
your credentials. If you do not need a release routine, you may set
_sysio_put_credentials to NULL.

In order to arrange the use of an alternate permission check the pointer
to _sysio_check_permission should be overwritten.

If any of these pointers are overwritten by the user, it must be
done prior to calling _sysio_init and may not be reset thereafter.
