adding asmbly to c code
Posted on 2003-03-02
hey there, this a lame question but how can i add a block of c code in borland C... i know asm whatever will add on line but how could i add like a block?
also are there any headers i should include for 8086 stuff so i can use my registers and what not
thanks for the help

Have you tried,
asm
{
}
>> also are there any headers i should include for 8086 stuff so i can use my registers and what not
In borland you can simply say,
union REGS regs;
regs.h.ah = 0x00;
For example, these two functions compile and run under Borland C,
void cls(void)
{
union REGS regs;
regs.h.ah=0x06;
regs.h.al=0x00;
regs.h.bh=0x07;
regs.h.ch=0x00;
regs.h.cl=0x00;
regs.h.dh=ROWS - 1;
regs.h.dl=COLS - 1;
int86(VIDEO,®s, ®s);
locate(0,0);
}
void locate(int col, int row)
{
union REGS regs;
regs.h.ah=0x02;
regs.h.bh=0x00;
regs.h.dh=row;
regs.h.dl=col;
int86(VIDEO,®s,®s);
}

here is small example on how do u do it with gnu c compiles gcc
__asm__ is used to make assembly calls
int foo( int a )
{
int b = 10;
a = 20;
__asm__ ("mov %1, %0" : "=r"
(a) : "r" (b) ); /* a = b */
return a;
}
This is simply copying b to a, and the return value is always 10.
and here is a link for inline assembly with gcc
