DEVNAME(3)              NetBSD Library Functions Manual             DEVNAME(3)

NAME
     devname -- get device name

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>
     #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.
     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
     string ``??''.

FILES
     /var/run/dev.db  Device database file.

SEE ALSO
     stat(2), dev_mkdb(8)

     The devname function call appeared in 4.4BSD.
