Class: MachO::Headers::FatArch

Inherits:
MachOStructure show all
Defined in:
lib/macho/headers.rb

Overview

Note:

"32-bit" indicates the fact that this structure stores 32-bit offsets, not that the Mach-Os that it points to necessarily are 32-bit.

32-bit fat binary header architecture structure. A 32-bit fat Mach-O has one or more of these, indicating one or more internal Mach-O blobs.
