Define Documentation

#define gettext   _conio_gettext

Define alias for _conio_gettext. If you want to use gettext function from some other library (e.g. GNU gettext) you have to define _CONIO_NO_GETTEXT_ so you won't get name conflict.

Enumeration Type Documentation

enum COLORS

Colors which you can use in your application. Enumeration values: BLACK  black color BLUE  blue color GREEN  green color CYAN  cyan color RED  red color MAGENTA  magenta color BROWN  brown color LIGHTGRAY  light gray color DARKGRAY  dark gray color LIGHTBLUE  light blue color LIGHTGREEN  light green color LIGHTCYAN  light cyan color LIGHTRED  light red color LIGHTMAGENTA  light magenta color YELLOW  yellow color WHITE  white color

Function Documentation

void _conio_gettext (  int  left, int  top, int  right, int  bottom, struct char_info *  buf )

Gets text from the screen. If you haven't defined _CONIO_NO_GETTEXT_ prior to including conio2.h you can use this function also under the gettext name. See also: char_info puttext Parameters: left  Left coordinate of the rectangle, inclusive, starting from 1. top  Top coordinate of the rectangle, inclusive, starting from 1. right  Right coordinate of the rectangle, inclusive, starting from 1. bottom  Bottom coordinate of the rectangle, inclusive, starting from 1. buf  You have to pass buffer of size (right - left + 1) * (bottom - top + 1) * sizeof(char_info).

void _setcursortype (  int  type  )

Sets the cursor type. See also: cursortypes Parameters: type  cursor type, under Win32 it is height of the cursor in percents

void cputsxy (  int  x, int  y, char *  str )

Puts string at the specified position. Parameters: x  horizontal position y  vertical position str  string

void delline (  void   )

Delete the current line (line on which is cursor) and then moves all lines below one line up. Lines below the line are moved one line up.

char* getpass (  const char *  prompt, char *  str )

Reads password. This function behaves like cgets. See also: cgets Parameters: prompt  prompt which will be displayed to user str  string for the password. str[0] have to contain length of the str - 3 Returns: &str[2], the password will be stored in str beginning at str[2], in str[1] will be length of the string without \0, at str[2 + str[1]] will be \0.

void gettextinfo (  struct text_info *  info  )

Returns information of the screen. See also: text_info

void gotoxy (  int  x, int  y )

Moves cursor to the specified position. Parameters: x  horizontal position y  vertical position

void highvideo (  void   )

Makes foreground colors light. If the current foreground color is less than DARKGRAY adds 8 to the its value making dark colors light. See also: COLORS lowvideo

void inittextinfo (  void   )

Call this if you need real value of normattr attribute in the text_info structure. See also: text_info

void insline (  void   )

Insert blank line at the cursor position. Original content of the line and content of lines below moves one line down. The last line is deleted.

void lowvideo (  void   )

Makes foreground colors dark. If the current foreground color is higher than LIGHTGRAY substracts 8 from its value making light colors dark. See also: COLORS highvideo

void movetext (  int  left, int  top, int  right, int  bottom, int  destleft, int  desttop )

Copies text. Parameters: left  Left coordinate of the rectangle, inclusive, starting from 1. top  Top coordinate of the rectangle, inclusive, starting from 1. right  Right coordinate of the rectangle, inclusive, starting from 1. bottom  Bottom coordinate of the rectangle, inclusive, starting from 1. destleft  Left coordinate of the destination rectangle. desttop  Top coordinate of the destination rectangle.

void normvideo (  void   )

Sets text attribute back to value it had after program start. It uses text_info's normattr value. See also: text_info

void putchxy (  int  x, int  y, char  ch )

Puts char at the specified position. Parameters: x  horizontal position y  vertical position ch  char

void puttext (  int  left, int  top, int  right, int  bottom, struct char_info *  buf )

Puts text back to the screen. See also: char_info _conio_gettext Parameters: left  Left coordinate of the rectangle, inclusive, starting from 1. top  Top coordinate of the rectangle, inclusive, starting from 1. right  Right coordinate of the rectangle, inclusive, starting from 1. bottom  Bottom coordinate of the rectangle, inclusive, starting from 1. buf  You have to pass buffer of size (right - left + 1) * (bottom - top + 1) * sizeof(char_info).

void textattr (  int  _attr  )

Sets attribute of text. Parameters: _attr  new text attribute

void textbackground (  int  color  )

Sets text background color. See also: COLORS Parameters: color  new background color

void textcolor (  int  color  )

Sets text foreground color. See also: COLORS Parameters: color  new foreground color

int wherex (  void   )

Reads the cursor X position. Returns: cursor X position

int wherey (  void   )

Reads the cursor Y position. Returns: cursor Y position
