Hi,
First of all, I hope this isn't the wrong newsgroup to post this in.
I am trying to learn the AT&T syntax of inline assembly. I need to convert
some inline assembly functions to the AT&T syntax because DJGPP doesn't
support the way I have it below. I can't figure it out
since I am unfamiliar with any kind of assembly language.
The code is below. If anyone could help convert it so I would know what to
do for future programs that use inline assembly,or if anyone could reccomend
a link to a site that can explain what I am trying to learn I would
appreciate it.

/*This is the code for four functions:
get_mode(),
save_mode(unsigned char mode),
pset(int x,int y,unsigned char color),
and
line(int x1,int y1,int x2,int y2,unsigned char color).*/
/*get_mode*/
unsigned char get_mode(void)
{
unsigned char mode;
_asm mov ah,0fh
_asm int 10h
_asm mov mode,al
return(mode);
}
/*save_mode*/
void set_mode(unsigned char mode)
{
_asm mov ah,00
_asm mov al,mode
_asm int 10h
}
/*pset*/
void pset(int x,int y,unsigned char color)
{
_asm mov ah,0ch
_asm mov al,color
_asm mov cx,x
_asm mov dx,y
_asm int 10h
}
/*line*/
void line(int x1,int y1,int x2,int y2,unsigned char color)
{
int x,y;
for(y=y1;y<=y2;y++)
pset(x1,y,color);
}
