/FUNCTIONPADMIN (Create hotpatchable image)
Tells the linker to prepare an executable image for hot patching.
Syntax
/FUNCTIONPADMIN[:size]
Arguments
size
The amount of padding to add to the beginning of each function in bytes. On x86 the default is 5 bytes of padding and on x64 the default is 6 bytes. On other targets a value must be provided.
Remarks
In order for the linker to produce a hotpatchable image, the .obj files must be compiled by using the /hotpatch (Create hotpatchable image) compiler option.
When you compile and link an image with a single invocation of cl.exe, /hotpatch implies /FUNCTIONPADMIN.

Open the project's Property Pages dialog box. For more information, see Set compiler and build properties.
Select the Configuration Properties > Linker > General property page.
