SYNTAX
#include <disktab.h>
struct disktab *
getdiskbyname(name)
char *name;
DESCRIPTION
The getdiskbyname subroutine takes a disk name (for example, rm03) and returns a structure describing its geometry information and the standard disk partition tables. All information obtained from the disktab(5) file.
< disktab.h > has the following form:
#define DISKTAB "/etc/disktab"
struct disktab {
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[8];
};
struct disktab *getdiskbyname();
