DEVNAME(3) Library Functions Manual DEVNAME(3)
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.
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.cdb Device database file.
The devname function call appeared in 4.4BSD.
