Defined in:

lib/macho/load_commands.rb

Overview

Represents a Load Command string. A rough analogue to the lc_str struct used internally by OS X. This class allows ruby-macho to pretend that strings stored in LCs are immediately available without explicit operations on the raw Mach-O data.

Instance Method Summary

• #initialize(raw_data, lc, lc_str) ⇒ LCStr constructor private

  A new instance of LCStr.

• #to_i ⇒ Fixnum

  The offset to the beginning of the string in the load command.

• #to_s ⇒ String

  A string representation of the LCStr.

Constructor Details

#initialize(raw_data, lc, lc_str) ⇒ LCStr

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

def initialize(raw_data, lc, lc_str)
  @raw_data = raw_data
  @lc = lc
  @lc_str = lc_str
  @str = @raw_data.slice(@lc.offset + @lc_str...@lc.offset + @lc.cmdsize).delete("\x00")
end
