Hello,

I am currently porting my graphic library from Borland C to DJGPP and I
would like to know how to call
a far pointer function in DJGPP. I've checked with others VESA packages but
all them seems to use
the interupt 0x10 for bank switching (slower than a simple call, in real
mode...protected mode not sure but I suppose it's also faster with a call. I
could be wrong on that?!).

My code (bank switching) worked fine in Borland C. (Intel Asm)

void far *bankptr;         /* Pointer to the banks switching function */

asm mov bx,write_win
asm mov dx,bank
asm call dword ptr bankptr

How do I code theses 4 lines in DJGPP?
Does DJGPP support that : call dword ptr bankptr part?

Thank you for any suggestions!
