vwaitforio(struct vnode *vp,
int slpflag, char *wmesg,
vwaitforio() call sleeps until all asynchronous writes associated with the vnode vp finish. This is used by functions that need to make sure that the writes they initiated have completed.
vwaitforio() call sleeps at priority
PRIBIO + 1. The slpflag,
wmesg, and slptimeo arguments
indicate flags to be passed to
This function must be called at splbio(9).
It may be important to ensure that no other process submits
asynchronous writes while a process is waiting for I/O on this vnode.
vwaitforio() may never return.
vwaitforio() function returns 0 on success. See tsleep(9) for possible error returns.
