poke

raw OCR

Stores an integer value at a memory location given by segment-.offset.

Defined in header <dos.h>

Syntax

#include <dos.h>
void poke(unsigned  segment, unsigned offset, int value);

Portability

DOSUNIXWindowsANSI CC++ only

Remarks

poke stores the integer value at the memory location segment-.offset.

If this routine is called when dos.h has been included, it will be treated as a macro that expands to inline code. If you don't include dos.h, or if you do include it and #undef poke, you'll get the function rather than the macro.

Return value

None.

Example

#include <dos.h>
#include <conio.h>
int main(void)
{
   clrscr0 ;
   cprintf("Make sure the  scroll lock key is off and press any key\r\n"
getchO ;
poke(OxOOOO,0x0417, 16);
cprintfC'The scroll  lock is now on\r\n");
return 0;
