pokeb

Stores a byte value at memory location segmentoffset.

Defined in header <dos.h>

Syntax

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

Portability

Remarks

pokeb stores the byte 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 pokeb, you'll get the function rather than the macro.

Return value

None.
