DEVNAME(3)			   BSD Library Functions Manual 		       DEVNAME(3)

     devname -- get device name

     Standard C Library (libc, -lc)

     #include <stdlib.h>
     #include <sys/stat.h>

     char *
     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 infor-
     mation is available, NULL is returned.

     The traditional display for applications when no device is found is the string ``??''.

     /var/run/dev.cdb  Device database file.

     stat(2), dev_mkdb(8)

     The devname function call appeared in 4.4BSD.
