This file includes five routines that may come in handy when working with
text-mode screens. They are all written in assembly language.
The following is included in the file wrap.h
/* directions for rollwrap */
#define LEFT_UP2
#define LEFT_DOWN3
#define RIGHT_UP0
#define RIGHT_DOWN1
typedef struct {
int x1, y1, x2, y2;
char attr;
} shiftwin;
void shift (shiftwin *win, int num); /* horizontal shift */
void scroll (shiftwin *win, int num); /* vertical scroll */
void roll (shiftwin *win, int num); /* vertical wrap */
void wrap (shiftwin *win, int num); /* horizontal wrap */
void rollwrap (shiftwin *win, int num, int dir); /* diagonal wrap */
/* end of wrap.h */
shift, scroll, roll, and wrap treat the parameter num as a signed integer.
rollwrap treates the parameter as unsigned. The parameter dir tells rollwrap
which directions to wrap the window.
I didn't include a shiftscroll() routine because this can easily be
accomplished by a shift followed immediately by a scroll (or vice-versa).
getscr contains internal routines called by shift, roll, wrap, and rollwrap.
These routines shouldn't be called by the application program.
The coordinates x1, y1, x2, and y2 are 1-relative, like the BGI text mode
coordinates.
These routines have been tested with Turbo C versions 1.0 and 1.5, but should
work equally well with Microsoft C.
Questions, comments, suggestions should be addressed to:
