| atomicBlock {hexView} | R Documentation |
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.
atomicBlock(type = "char", width = NULL, machine = "hex",
size = switch(type, char = 1, int = 4, real = 8),
endian = "little", signed = TRUE)
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. |
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),
integer4 (int, long),
integer8 (long long),
real4 (float),
real8 (double).
