source: trunk/Cocoa/F-Script Anywhere/Source/mach_inject/mach_inject.h@ 219

Last change on this file since 219 was 217, checked in by rchin, 18 years ago
  • Updated to new mach_inject with support for x86
  • Updated nib files to 10.2+ format so that future updates to the f-script framework won't break fsa
  • Adjusted some code to work with the new x86 mach_inject (sends an additional argument)
  • Updates code to work with newer defines in cctools

12 This package, coded in C to the Mach API, allows you to "inject" code into
13 an arbitrary process. "Injection" means both 1) copying over the necessary
14 code into the target's address space and 2) remotely creating a new thread
15 to execute the code.
