getdiskbyname(3)getdiskbyname(3)NAMEgetdiskbyname - Get the disk description using a disk name
SYNOPSIS
#include <sys/disklabel.h> #include <sys/types.h>
struct disklabel *getdiskbyname(
char *name ); int getdiskbyname_r(
char *name,
struct disklabel *disk,
char *book,
int boot_len );
LIBRARY
Standard C Library (libc)
PARAMETERS
Specifies a common name for the disk drive whose geometry and partition
characteristics are sought. Points to the structure that will contain
the returned disk description. Points to the buffer that will contain
the optional names of the primary and secondary bootstraps. Specifies
the length of boot. This should be BUFSIZ.
DESCRIPTION
Operations supported by the getdiskbyname function are also supported
by the createlabel function. See createlabel(3). The getdiskbyname and
getdiskbyname_r functions are supported only for backward compatibility
with Digital UNIX Version 4.0 and earlier versions. These functions
will be retired in a future release of Tru64 UNIX.
The getdiskbyname() function uses a disk (disk drive) name to return a
pointer to a structure that describes the geometry and standard parti‐
tion characteristics of the named disk drive. Information obtained from
the /etc/disktab database file is written to the type disklabel struc‐
ture space referenced by the returned pointer.
The getdiskbyname_r() function is the reentrant version of getdiskby‐
name(). Upon successful completion, getdiskbyname_r() returns a value
of 0 (zero); the returned structure is pointed at by disk. Upon error,
it returns a value of -1, and may set errno to [EINVAL].
RETURN VALUES
Upon successful completion, the getdiskbyname() function, returns a
pointer to a type disklabel structure.
ERRORS
Either disk or boot is NULL, or boot_len is not equal to BUFSIZ.
