Prepares an image for hotpatching.
/FUNCTIONPADMIN[:space]
Remarks
where,
- space (optional) 
 The amount of padding to add to the beginning of each function, 5, 6, or 16. x86 images require five bytes of padding, x64 images require 6 bytes, and images built for the Itanium Processor Family require 16 bytes of padding at the beginning of each function.- By default, the compiler will add the correct amount of space to the image, based on the machine type of the image. 
In order for the linker to produce a hotpatchable image, the .obj files must have been compiled with /hotpatch (Create Hotpatchable Image).
When you compile and link an image with a single invocation of cl.exe, /hotpatch implies /functionpadmin.
