Hi list...
I'm using this little program to find out which blocks are use by a particular file: int main(int argc, char **argv) { int fd, i, block, blocksize, bcount; struct stat st;
assert(argv[1] != NULL); assert(fd=open(argv[1], O_RDONLY)); assert(ioctl(fd, FIGETBSZ, &blocksize) == 0); assert(!fstat(fd, &st)); bcount = (st.st_size + blocksize - 1) / blocksize; printf("File: %s Size: %d Blocks: %d Blocksize: %d\n", argv[1], st.st_size, bcount, blocksize); for(i=0;i < bcount;i++) { block=i; if (ioctl(fd, FIBMAP, &block)) { printf("FIBMAP ioctl failed - errno: %s\n", strerror(errno)); } printf("%3d %10d\n", i, block); } close(fd); }
This works fine for regular files, but not for directorys. Both ioctl's, FIGETBSZ and FIBMAP, are implemented for regular files only.
Is there a patch to make this FIGETBSZ and FIBMAP work on directorys too? Or alternativly, is there a way to find out which blocks are used by a directory?
Thanks for answers in advance Sebastian.
