NAME¶vcount, count_dev — get total number of references to a device
#include <sys/vnode.h> int
vcount(struct vnode *vp); int
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 dev_t rather than a 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)
