cgread
CGREAD(3) BSD Library Functions Manual CGREAD(3)
NAME
cgread, cgread1, cgwrite1 -- read/write cylinder groups of UFS disks
LIBRARY
UFS File System Access Library (libufs, -lufs)
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
#include <ufs/ufs/ufsmount.h>
#include <ufs/ufs/dinode.h>
#include <ufs/ffs/fs.h>
#include <libufs.h>
int
cgread(struct uufsd *disk);
int
cgread1(struct uufsd *disk, int c);
int
cgwrite1(struct uufsd *disk, int c);
DESCRIPTION
The cgread() and cgread1() functions provide cylinder group reads for libufs(3) consumers. The cgread1() function reads from one cylinder
group, specified by c into the d_cg field of a userland UFS disk structure. It sets the d_lcg field to the cylinder group number c.
The cgread() function operates on sequential cylinder groups. Calling the cgread() function is equivalent to calling cgread1() with a cylin-
der group specifier equivalent to the value of the current d_ccg field, and then incrementing the d_ccg field.
The cgwrite1() function stores cylinder group specified by c from d_cg field of a userland UFS disk structure on disk.
RETURN VALUES
Both functions return 0 if there are no more cylinder groups to read, 1 if there are more cylinder groups, and -1 on error.
ERRORS
The function cgread() may fail and set errno for any of the errors specified for the library function bread(3).
The function cgread1() has semantically identical failure conditions to those of cgread().
The function cgwrite1() may fail and set errno for any of the errors specified for the library function bwrite(3).
SEE ALSO
bread(3), bwrite(3), libufs(3)
HISTORY
These functions first appeared as part of libufs(3) in FreeBSD 5.1.
