I do not like the function ** names very much, but the first version started as a rewrite of Borland's ** conio, and, even if the interface has changed, the names did not. ** ** The interface does direct screen I/O, so it is fast enough for most ** programs. I did not implement text windows, since many applications do ** not need them and should not pay for the additional overhead. It should ** be easy to add text windows on a higher level if needed, ** ** Most routines do not check the parameters. This may be unfortunate but is ** also related to speed. The coordinates are always 0/0 based. */ #ifndef _CONIO_H #define _CONIO_H #include <stdarg.h> #include <target.h> /*****************************************************************************/ /* Functions */ /*****************************************************************************/ void clrscr (void); /* Clear the whole screen and put the cursor into the top left corner */ unsigned char kbhit (void); /* Return true if there's a key waiting, return false if not */ void __fastcall__ gotox (unsigned char x); /* Set the cursor to the specified X position, leave the Y position untouched */ void __fastcall__ gotoy (unsigned char y); /* Set the cursor to the specified Y position, leave the X position untouched */ void __fastcall__ gotoxy (unsigned char x, unsigned char y); /* Set the cursor to the specified position */ unsigned char wherex (void); /* Return the X position of the cursor */ unsigned char wherey (void); /* Return the Y position of the cursor */ void __fastcall__ cputc (char c); /* Output one character at the current cursor position */ void __fastcall__ cputcxy (unsigned char x, unsigned char y, char c); /* Same as "gotoxy (x, y); cputc (c);" */ void __fastcall__ cputs (const char* s); /* Output a NUL-terminated string at the current cursor position */ void __fastcall__ cputsxy (unsigned char x, unsigned char y, const char* s); /* Same as "gotoxy (x, y); puts (s);" */ int cprintf (const char* format, ...); /* Like printf(), but uses direct screen output */ int __fastcall__ vcprintf (const char* format, va_list ap); /* Like vprintf(), but uses direct screen output */ char cgetc (void); /* Return a character from the keyboard.
