CreateOptions.setSigBlockLen

void setSigBlockLen(DarDeltaSigBlockFunc fsFunction,
          ulong  multiplier =  1,
          ulong  divisor =  1,
          uint  minBlockLen =  2048,
          uint  maxBlockLen =  0)

@safe

Sets the signature block length calculation parameters.

The block size used for delta signatures is calculated from file size using: block_size = multiplier/divisor * fs_function(filesize)

The result is clamped to minBlockLen, maxBlockLen (unless maxBlockLen is 0).

Parameters

`fsFunction`	function type for deriving block size from file size
`multiplier`	function-dependent multiplier (default: 1)
`divisor`	function-dependent divisor, cannot be zero (default: 1)
`minBlockLen`	minimum block length in bytes (default: 2048)
`maxBlockLen`	maximum block length in bytes, 0 = no limit (default: 0)
