INT 86 Int86() is a C function that allows to call interrupts in the program. prototype in dos.h In and out register must be type of REGS. REGS is a built in UNION declaration in C. It is defined in the header file <DOS.h>
pick one: int main (void); int main (int argc, char **argv); int main (int argc, char **argv, char **envp);
No he dos int if he did I whould die
1. syntax error2. int 21h -- assembly statement in x86 to access a MS-DOS service
#include <stdlib.h> int main() { system("dir"); return 0; }
%p prints a pointer, %x prints an integer. They may be similar, but not the same. Eg.printf ("ptr=%p int=%d\n", main, (int)main);DOS: ptr=0F01:0010 int=10Windows: ptr=:0F010010 int=F010010
Blinking text in DOS, compiled with Turbo C #include int main() { int color; textattr(128 + 10); cprintf("This is blinking text\n"); return 0; }
Interrupt 20 ( AKA INT 20, int 20h, INT 20H) is the 33rd entry in the standard PC interrupt table. The '20' is hexadecimal notation (hence the use of the H or h, which may actually be required by some assemblers whereas others assume entries are hexadecimal) for decimal thirty-two (32) but counting starts from zero, as is usually the case in Computer Science.Int 20 is known as "DOS Terminate" and will end execution of the code at that point and return control to DOS (or the DOS-like environment which called it). It looks at the CS register (a standard 80x86 register which was intended to 'point' to the segment where the code was loaded - Code Segment) and returns nothing by way of register or stack.Simple Answer: this is an instruction used in very small and typically very old DOS programs to terminate themselves quickly and with a minimum of effort, it probably ought not to be used today, research Int 21 instead (the so-called 'DOS Interrupt').N.B.: This instruction could also refer to other architectures and thus be very different, e.g. AIX, VMS, etc. My answer is PC & DOS specific as this is the most likely context for this question.
