NAMEvcount, count_dev - get total number of references to a device
SYNOPSIS#include <sys/param.h> #include <sys/time.h> #include <sys/conf.h> #include <sys/vnode.h> int vcount(struct vnode *vp); int count_dev(dev_t dev);
DESCRIPTIONvcount() 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 VALUESvcount() and count_dev() both return the number of references to the device.
