A function Symbol referring to an external location.
This Symbol is intended to label functions that have not been mapped directly into the image being analyzed. It holds a level of indirection between the address the image expects the symbol to be at and a placeholder address the system hangs meta-data on.
Construct given a placeholder address.
sc | is the Scope containing the Symbol |
ref | is the placeholder address where the system will hold meta-data |
nm | is the name of the Symbol |

private |
Create a name and data-type for the Symbol.
Build name, type, and flags based on the placeholder address.
