Add a function to open quick menu without triggering the button about vita-headers

Edit2 > It's just a function to unlock what's locked. Doesn't open quick menu.

Currently, no such function is known. Or does not exist.
It may be found by reverse engineering SceShell stuff etc., but SceShell is 3MB and it is difficult to reverse engineer.

excuse me for my ignorance, but isn't it possible to manually call the function (determined using call stack or stack trace?) which gets called on physically holding the PS home button?

Edit:
Ah, I see what you mean, it isn't possible at the moment, I guess I can close this issue then?

How

1. Call SceShell's DisplayQuickMenu function directly from user
2. Call ksceCtrlSetButtonEmulation from kernel

I am guessing that the 2nd method won't work because it's the same thing as pressing the home button physically, the power button when pressed (due to being stuck at pressed) prevents the quick menu from opening somehow.

I am going to attempt the 1st method and see what I come up with. Thanks.

Edit:
Also, I have already tried ReVita and mapping the home key to another button, and it is most probably also using the same function (ksceCtrlSetButtonEmulation) to emulate key presses. The quick menu doesn't show up when holding the mapped button, and also using the home button in a combination works just fine for other system actions, but there is no system action defined to bring up the quick menu.

Edit 2:
Will this function bring up the quick menu (args being unlock mode, quick menu type) ?
