// Script to apply any changes the user has made to class virtual function signatures, ie ones they
|
|
// have edited in the listing. To run the script, put the cursor on any member of the desired class in
|
|
// the listing then run the script. For each function signature in the given class that differs from
|
|
// the associated function definition in the data type manager, the script will update the listing
|
|
// function signatures of any related virtual vunctions (ie parents and children) and update related
|
|
// data types such as function definitions of the given class and related classes and also field names
|
|
// in related vftable structures.
|
|
// Note: The script will not work if the vftable structures were not originally applied to
|
|
// the vftables using the RecoverClassesFromRTTIScript.
|
|
// At some point, the Ghidra API will be updated to do this automatically instead of needing the script to do so.
