.Dd May 23, 2000 .Dt LFS_BMAPV 2 .Os .Sh NAME .Nm lfs_bmapv .Nd retrieve disk addresses for arrays of blocks .Sh LIBRARY .Lb libc .Sh SYNOPSIS n sys/types.h n ufs/lfs/lfs.h .Ft int .Fn lfs_bmapv "fsid_t *fsidp" "BLOCK_INFO *blkiov" "int blkcnt" .Sh DESCRIPTION .Fn lfs_bmapv fills in the bi_daddr field for every block listed in the block array .Fa blkiov with the disk address corresponding to the logical block .Fa bi_lbn of the file with inode .Fa bi_inode . If .Fa bi_lbn is LFS_UNUSED_LBN, the disk location of the inode block containing the file's inode will be returned in .Fa bi_daddr instead.
p The .Fa fsidp argument contains the id of the file system to which the inodes and blocks belong. The .Fa blkiov argument is an array of BLOCK_INFO structures (see below). The .Fa blkcnt argument determines the size of the .Fa blkiov array. d -literal typedef struct block_info { ino_t bi_inode; /* inode # */ ufs_daddr_t bi_lbn; /* logical block w/in file */ ufs_daddr_t bi_daddr; /* disk address of block */ time_t bi_segcreate; /* origin segment create time */ int bi_version; /* file version number */ void *bi_bp; /* data buffer */ int bi_size; /* size of the block (if fragment) */ } BLOCK_INFO; .Ed .Sh RETURN VALUES .Fn lfs_bmapv returns 0 on success, or -1 on error. .Sh ERRORS An error return from .Fn lfs_bmapv indicates: l -tag -width Er t Bq Er EFAULT .Fa fsidp points outside the process's allocated address space. t Bq Er EINVAL .Fa *fsidp does not specify a valid file system. .El .Sh SEE ALSO .Xr lfs_markv 2 , .Xr lfs_segclean 2 , .Xr lfs_segwait 2 , .Xr lfs_cleanerd 8 .Sh HISTORY The .Fn lfs_bmapv function call appeared in x 4.4 .
