[DONE]How to get button status in code?

[rnynoise]

Hi there, I'm sorry for asking such a simple question, because I'm a green hand to PPSSPP codes, and just begin from yestoday. =(
I'm working on the "0xD" cheat code now, you know there are some code depend on button state, I tried to find this by myself but failed...
Here are an example:
int buttonStatus; // ut32 buttonStatus? be used as a buffer to save button status
when TRIANGLE and CIRCLE is push, the value should be like this
buttonStatus = 0x00001000 + 0x00002000 // should be 0x00003000
I just want to know how to get the value of "0x00001000" and "0x00002000" or "0x00003000" in code?
thx for you read, and do me a favor plz
