// Automatically creates a structure definition based on the references seen to the structure
|
|
// To use this, place the cursor on a function parameter for example func(int *this),
|
|
// (for a C++ this call function)
|
|
// This script will automatically create a structure definition for the pointed at structure
|
|
// and fill it out based on the references found by the decompiler.
|
|
//
|
|
// If the parameter is already a structure pointer, any new references found will be added
|
|
// to the structure, even if the structure must grow.
|
|
//
|
|
// Eventually this WILL be put into a global type analyzer, but for now it is most useful.
|
|
//
|
|
// This script assumes good flow, that switch stmts are good.
|
|
//
|
|
// This script CAN be used in the decompiler by assigning a Binding a Keyboard key to it, then
|
|
// placing the cursor on the variable in the decompiler that is a structure pointer (even if it
|
|
// isn't one now, and then pressing the Quick key.
