NAME vcount, count_dev - "get total number of references to a device" CONTENTS Synopsis Description Return Values See Also Authors SYNOPSIS .In sys/param.h .In sys/time.h .In sys/conf.h .In sys/vnode.h int vcount "struct vnode *vp" int count_dev "dev_t dev" DESCRIPTION vcount is used to get the number of references to a particular device. It allows for the fact that multiple vnodes may reference the same device. count_dev does the same thing as vcount, but takes a .Vt dev_t rather than a .Vt "struct vnode" pointer as an argument. RETURN VALUES vcount and count_dev both return the number of references to the device. SEE ALSO VFS(9), vnode(9) AUTHORS
