GETDISKBYNAME(3)          NetBSD Programmer's Manual          GETDISKBYNAME(3)


NAME

     getdiskbyname, setdisktab - get generic disk description by its name


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <sys/types.h>
     #include <sys/disklabel.h>
     #include <disktab.h>

     int
     setdisktab(char *name);

     struct disklabel *
     getdiskbyname(const char *name);


DESCRIPTION

     The getdiskbyname() function takes a disk name (e.g.  `rm03') and returns
     a prototype disk label describing its geometry information and the stan-
     dard disk partition tables.  All information is obtained from the
     disktab(5) file.

     The setdisktab() function changes the default file name from /etc/disktab
     (aka _PATH_DISKTAB) to name.


RETURN VALUES

     getdiskbyname() returns a null pointer if the entry is not found in the
     current disktab file.

     setdisktab() returns 0 on success and -1 if name is a null pointer or
     points to an empty string.


FILES

     /etc/disktab  the default database of disk types.


SEE ALSO

     disklabel(5), disktab(5), disklabel(8)


HISTORY

     The getdiskbyname() function appeared in 4.3BSD.

     The setdisktab() function appeared in NetBSD 1.4.


BUGS

     The getdiskbyname() function leaves its results in an internal static ob-
     ject and returns a pointer to that object.  Subsequent calls will modify
     the same object.
