GETDISKBYNAME(3)					   BSD Library Functions 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
     standard disk partition tables.  All information is obtained from the disktab(5) file.

     The setdisktab() function changes the default disktab 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 object and returns a pointer to that object.  Subsequent calls will
     modify the same object.

NAME

       getdiskbyname() - get disk description by its name

SYNOPSIS

   Obsolescent Interface
DESCRIPTION

       takes a disk name (such as hp7959B) and returns a pointer to a structure that describes its geometry information and the standard disk par-
       tition tables.  All information is obtained from the disktab database file (see disktab(4)).

       The contents of the structure include the following members.  Note that there is not necessarily any correlation between the  placement	in
       this list and the order in the structure.

	      char    *d_name;		  /* drive name */
	      char    *d_type;		  /* drive type */
	      int     d_secsize;	  /* sector size in bytes */
	      int     d_ntracks;	  /* # tracks/cylinder */
	      int     d_nsectors;	  /* # sectors/track */
	      int     d_ncylinders;	  /* # cylinders */
	      int     d_rpm;		  /* revolutions/minute */
	      struct  partition {
		      int     p_size;	  /* #sectors in partition */
		      short   p_bsize;	  /* block size in bytes */
		      short   p_fsize;	  /* frag size in bytes */
	      } d_partitions[NSECTIONS];

DIAGNOSTICS

       A NULL pointer is returned in case of an error, or if name is not found in the disktab database file.

WARNINGS

       The  return value for points to data whose content is overwritten by each call.	is an obsolescent interface supported only for compatibil-
       ity with existing DCE applications. New multithreaded applications should use
