atomicBlock

Create an atomicBlock Object

Description

This function creates an "atomicBlock" object, which is a description of a block of binary data. This can be used as part of a description of a binary format.

Usage

atomicBlock(type = "char", width = NULL, machine = "hex",
            size = switch(type, char = 1, int = 4, real = 8),
            endian = "little", signed = TRUE)

Arguments

`type`	How the block of binary data will be interpreted. either `"char"` (an ASCII character), `"int"` (an integer), or `"real"` (a floating point number).
`width`	The number of bytes to print per row when displaying the block.
`machine`	How to print each byte when displaying; either `"hex"` or `"binary"`.
`size`	The number of bytes used to generate each value when interpreting the raw binary as character or numeric data.
`endian`	The endianness of the binary data; used when interpreting bytes as numeric values.
`signed`	Whether the bytes should be interpreted as a signed numeric value.

Details

An "atomicBlock" object describes a binary block representing a single value.

Several standard binary types are predefined (with common C type equivalents in brackets): ASCIIchar (char), integer1 (signed char), integer2 (short), integer3, integer4 (int, long), integer8 (long long), real4 (float), real8 (double).

Value

An "atomicBlock" object.
