question: the number of bytes that are free on the file system , including reserved blocks that are not available to normal applications . most applications will want to use #getavailablebytes instead . concode_field_sep StructStatVfs mStat concode_field_sep long getAvailableBlocksLong concode_elem_sep long getTotalBytes concode_elem_sep long getBlockSizeLong concode_elem_sep long getBlockCountLong concode_elem_sep int getBlockSize concode_elem_sep int getFreeBlocks concode_elem_sep int getAvailableBlocks concode_elem_sep StructStatVfs doStat concode_elem_sep void restat concode_elem_sep int getBlockCount concode_elem_sep long getFreeBlocksLong concode_elem_sep long getAvailableBytes
target: long function ( ) { return mStat . f_bfree * mStat . f_bsize ; }
