LIBRARY

SYNOPSIS

     #include <sys/stat.h>

     char *
     devname(dev_t dev, mode_t type);


DESCRIPTION

     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.

     able, NULL is returned.

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