getdiskbyname(3)					     Library Functions Manual						  getdiskbyname(3)

NAME

       getdiskbyname, getdiskbyname_r - Get the disk description using a disk name

LIBRARY

       Standard C Library (libc)

SYNOPSIS

       #include <sys/disklabel.h> #include <sys/types.h>

	struct disklabel *getdiskbyname(      char *name);

	int getdiskbyname_r(	  char *name,	   struct disklabel *disk,	char *boot,	 int boot_len);

PARAMETERS

       Specifies a common name for the disk drive whose geometry and partition characteristics are sought.  Points to the structure that will con-
       tain 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 The getdiskbyname and getdiskby-
       name_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 par-
       tition characteristics of the named disk drive. Information obtained from the /etc/disktab database file is written to the  type  disklabel
       structure space referenced by the returned pointer.

       The  getdiskbyname_r() function is the reentrant version of getdiskbyname().  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.
