devname - get device name
Standard C Library (libc, -lc)
devname(dev_t dev, mode_t type);
The devname() function returns a pointer to the name of the block or
character device in ``/dev'' with a device number of dev, and a file type
matching the one encoded in type which must be one of S_IFBLK or S_IFCHR.
The device name is cached so that multiple calls with the same dev and
type do not require additional queries of the device database file. If
no device matches the specified values, or no information is available,
NULL is returned.
The traditional display for applications when no device is found is the
/var/run/dev.db Device database file.
The devname function call appeared in 4.4BSD.
