NAME

getdiskbyname( ) - get disk description by its name

SYNOPSIS

#include <disktab.h>

struct disktab *getdiskbyname(const char *name);

Obsolescent Interface

int getdiskbyname_r(

const char *name,

struct disktab *result,

char *buffer,

int buflen);

DESCRIPTION

getdiskbyname()

takes a disk name (such as hp7959B) and returns a pointer to a structure that

describes its geometry information and the standard disk partition tables. All information is obtained

from the disktab database ﬁle (see disktab (4)).

The contents of the structure

disktab include the following members. Note that there is not neces-

sarily 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];

The constant NSECTIONS is deﬁned in <disktab.h>.

Obsolescent Interface

getdiskbyname_r()

gets disk description by its name.

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

getdiskbyname() points to data whose content is overwritten by each call.

getdiskbyname_r() is an obsolescent interface supported only for compatibility with existing DCE

applications. New multithreaded applications should use getdiskbyname()
