To have your program find out if the system has a keystick inserted, use the API GetKeyInserted (use the uppercase and lowercase shown).
There are no restrictions on the use of this command.
This API returns the following information:
| Bytes 0 and 1 | Bytes 2 and 3 | Bytes 4 through 4+N |
|---|---|---|
| 16-bit return code 0 => Command successful 1 => Command unsuccessful |
16-bit additional data length N N = size of ASCII return value (does not count end of string NULL) |
True or False |
