atomicBlock: Create an atomicBlock Object

In pmur002/hexview: Viewing Binary Files

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.
