Hi everyone ...
PLEASE help me with my problem, because its been bugging me for ages.
Im trying to code a NetBIOS game using DJGPP/ALLEGRO. I am told
in a book that I need to call interrupt INT 5Ch, with ES:BX pointing to
my NCB structure. After reading the FAQ (section 18.2) I guessed that
I dont need to put the BX bit in?
Anyway, here's some 16-bit code a friend gave me that works on my old
Turbo-C 16-bit compiler ...
nbexec ( NCB *zncb ){
union REGS inregs , outregs ;
struct SREGS segregs;
segregs.es = FP_SEG ( zncb );
inregs.x.bx = FP_OFF ( zncb );
int86x ( 0x5c , &inregs , &outregs , &segregs );
return ( outregs.h.al );
}
And here's my port THAT DOESNT WORK! (IT JUST CRASHES :)
int net_exec(NCB *ncb){
union REGS inregs,outregs;
inregs.w.bx=ncb;
int86(0x5c,&inregs,&outregs);
return(outregs.h.al);
}
I'm sure that you experts could help me out here ... and its only a few
lines of code ... SO PLEASE SOMEONE HELP ME!
I'm told to put my pointer into ES:BX and then call INT 5Ch, and the
result is returned in AL.
But I dont know how :(
PLEASE HELP!
Thanks in advance!
