setBlock

 

 

Overview

The setBlock function sets the specified blocks to occupied in the Bit Vector. Vacant blocks are represented by 0 bits, while occupied blocks are represented by 1 bits.

For example:

(setBlock bitVector i 3)

The above freeBlock invocation sets the 3 blocks (starting at bit index i) to be occupied. After this invocation:

bitVector[i] = 1

bitVector[(+ i 1)] = 1

bitVector[(+ i 2)] = 1

Usage

The setBlock function is used to allocate block space in a BitVector used to manage a memory space or disk space.

 

Syntax

Expression:

(setBlock bitVector blockIndex blockCount)


Arguments Name Type Description
Argument:bitVectorBitVector The BitVector in which a consecutive string of blocks to be set occupied.
Argument:blockIndexInteger The starting bit index of the consecutive string of blocks to be set occupied.
Argument:blockCountInteger The number of consecutive blocks to be set occupied.

Returns:

The block index after the last occupied block.
