Hi there,
               I'm brand new to DJGPP programming and have a question. In a
Turbo C program I have the following code to put the address of the 'info'
structure across the registers es:di before and interrupt is called. My
question is - in 32-bit protected mode how do I go about doing the same
thing? The interrupt called is one of the VESA ones, does it want a real
mode address or the protected mode address. How do I pass these to it? Is
this the same for all interrupts where addresses are passed or recieved?

/* */
sregs.es = FP_SEG (&info);  /* segment of data structure */
regs.x.di = FP_OFF (&info);   /* offset of data structure */
/* interrupt called */


One other thing, please could anyone recommend a tutorial or website where I
can find information on, and about programming in 32-bit p. mode.

Thanks a bunch
Graham.
