Function RTGetGMode

This function can retrieve the current BIOS graphics mode:

int RTGetGMode(void);

If the GMode directive was used, this function returns the graphics mode set during the boot process. Please note that the returned mode may actually be a text mode (e.g., value 3 or 7), if none of the graphics modes were accepted by the BIOS. For systems booted in UEFI mode, value 0xFFFF is returned.

On targets which do not have a BIOS, value 0 or -1 is returned.
