[ Top ]

void makeWriterRemoveBlocks(
array
$blocks, [int

int	`$seek`	—	relative pos of the block
array	`$blocks`	—	Lengths of the blocks. The first one will be discarded, the second one kept, the third one discarded... If the sum of the blocks is less than the size of the file, the comportment is the same as if a last block was set in the array to reach the size of the file if $length is -1, the file is truncated from the specified pos It is possible to specify blocks of size 0
