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 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];
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().
