Function Documentation

mach_error_t mach_inject (  const mach_inject_entry  threadEntry, const void *  paramBlock, size_t  paramSize, pid_t  targetProcess, vm_size_t  stackSize )

Starts executing threadEntry in a new thread in the process specified by targetProcess. Bug: We only want an 8K default, fix the plop-in-the-middle code below. Stack math should be more sophisticated than this (ala redzone). Todo: Would be nice to just allocate one block for both the remote stack and* the remoteCode (including the parameter data block once that's written. Definition at line 32 of file mach_inject.c.

mach_error_t machImageForPointer (  const void *  pointer, const void **  image, unsigned long *  size )

Given a pointer, returns its Mach-O image and image size. Parameters: pointer  -> Required pointer. image  <- Optional returned pointer to image (really a mach_header). size  <- Optional returned size of the image. Returns: <- mach_error_t Definition at line 161 of file mach_inject.c. References ASSERT_CAST, and err_threadEntry_image_not_found. Referenced by mach_inject().
