SYNOPSIS

#include <disktab.h>

struct disktab ∗
getdiskbyname(name)
char ∗name;

DESCRIPTION

Getdiskbyname takes a disk name (e.g., rm03) and returns a structure describing its geometry information and the standard disk partition tables.  All information is obtained from the disktab(5) file. 

The form of <disktab.h> is as follows:
