35 .Nd retrieve disk addresses for arrays of blocks
42 .Fn lfs_bmapv "fsid_t *fsidp" "BLOCK_INFO *blkiov" "int blkcnt"
45 fills in the bi_daddr field for every block listed in the block array
47 with the disk address corresponding to the logical block
49 of the file with inode
53 is LFS_UNUSED_LBN, the disk location of the inode block containing the
54 file's inode will be returned in
60 argument contains the id of the file system to which the inodes and
64 argument is an array of BLOCK_INFO structures (see below).
67 argument determines the size of the
71 typedef struct block_info {
72 ino_t bi_inode; /* inode # */
73 ufs_daddr_t bi_lbn; /* logical block w/in file */
74 ufs_daddr_t bi_daddr; /* disk address of block */
75 time_t bi_segcreate; /* origin segment create time */
76 int bi_version; /* file version number */
77 void *bi_bp; /* data buffer */
78 int bi_size; /* size of the block (if fragment) */
83 returns 0 on success, or \-1 on error.
91 points outside the process's allocated address space.
94 does not specify a valid file system.
