CONIO.H

Functions

cgets - cgets read a string of characters from the

console and stores the string(and the string length) in

the location *str.

clreol - clears all characters from the cursor position

to the end of the line within the current text window,

without moving the cursor.

clrscr - clrscr clears the current text window and

places the cursor in the upper left-hand corner (at

position 1,1).

cprintf - sends formatted output to the text window on

the screen.

cputts - write the null-terminated string str to the

current text window. It does not append a newline

character.

cscanf - scans and formats input from the console.

delline - deletes the line containing the cursor and

moves all lines below it one line up.

getch - gets a character from the console but does not

echo to the screen.

getche - gets a character from the console and echoes

to the screen.

getpass - reads a password from the system console,

after prompting with the null-terminated string prompt

and disabling the echo.

gettext - copies text from text-mode screen to memory

gettextinfo - fills in a structure with the current text video information.

gotyxy - moves the cursor to the given position in the

current text window.

highvideo - selects high-intensity text characters

insline - inserts and empty line in the text window at

the cursor position using the current text background

color.

inp - reads a byte from a hardware port

inport - inport works just like the 80x86 instruction

IN. It reads the low byte of a word from portid, the high byte from portid + 2

inportb -  is a macro that reads a byte

inpw - reads a word from a hardware port

kbhit - checks to see if a keystroke is currently available.

lowvideo - selects low-intensity text characters

normvideo -      selects normal-intensity text characters

outp         -outputs a byte to a hardware port

outport     - works like the 80x86 instruction OUT. It writes the low byte if value to portid, the high byte to portid + 1

outportb   - is a macro that writes value.

outpw       - outputs a word to a hardware port.

putch       - outputs the character c to the currect text  window. It is a text-mode function that performs direct video output to the console.

puttext     - copies text from memory to text-mode screen.

setcursortype    - selects the cursor appearance.

textattr             - sets text attributes for text-window functions

textbackground         - selects a new text background color

textcolor           - selects a new character color in text mode.

textmode           - selects a specific text mode.

ungetch            - pushes the character ch back to the console, causing ch to be the next character read.

wherex     - returns the x-coordinate of the current cursor  position (within the current text window.)

wherey     - returns the y-coordinate of the current cursor  position (within the current text window.)

window     - defines active text-mode window

IOSTREAM.H

 - Declares the C++2.0 basic streams

 - Replaces the older STREAM.H header file.

Classes

ios    - provides operations common to both input and

output.

iostream_withassign - This class is an iostream with

two added assignment operators.

istream_withassign    - This class is an istream with two

added assignment operators.

ostream_withassign   - This class is an ostream with two

added assignment operators.

iostream                    - This class is a mixture of its base classes

fstream and strstream, allowing both input and output

on stream.

istream     - Provides formatted and unformatted input from

a derived class of class streambuf via data member bp

of base class ios.

ostream     - Provides formatted and unformatted output to

a derived class of class streambuf, This occurs via 

data member bp of base class ios.

streambuf         - This is a buffer-handling class.

- Your applications gain access to buffer and buffering functions through a pointer to streambuf that is set by ios.

STDIO.H

Functions

clearerr - resets the names stream's error and end-of-file indicators to 0.

fclose - closes the named stream

fcloseall - closes all open streams except stdin, stdout, stdprn, stderr, and stdaux.

fdopen - associates a stream with a file handle.

feof - is a macro that tests the given stream for an end-of-file indicator.

ferror - is a macro that tests the given stream for a  read or write error.

fflush - If the given stream has buffered output, fflush writes the output for stream to the associated file.

fgetc - gets a character from a stream.

fgetchar - get a character from stdin

fgetpos - gets the current file pointer position.

fgets - gets a string from a stream.

fileno - is a macro that returns the file handle for the stream.

flushall - clears all buffer associated with open input  streams, and writes all buffers associated with open output streams to their respective files.

fopen - opens a stream.

fprintf - sends formatted output to a stream.

fputc - outputs a character to a stream.

fputchar - outputs a character to stdout.

fputs - outputs a string to a stream.

fread - reads a specified number of equal-sized data items from an input stream into a block.

freopen - associates a new file with an open stream.

fscanf - Scans and formats input from a stream.

fseek - sets the file pointer associated with a stream to a new position.

fsetpos - positions the file pointer of a stream.

ftell - returns the current file pointer for stream.

fwrite - appends a specificied number of equal-sized data items to an output file.

getc - is a macro that gets one character from a stream.

getchar - is a macro that gets a character from stdin.

gets - gets a string from stdin.

getw - gets an integer from stream.

perror - prints to the stderr stream (nirmally the console) the system error message for the last library routine that produced  the error.

printf - sends formatted output to a stdin.

putc - is a macro that outputs a character to a stream.

putchar - is a macro that outputs a charater on stdout.

puts - outputs a string to stdout (and appends a newline character).

putw - outputs an integer on a stream.

strerror - returns a pointer to an error message string.

_strerror - builds a customized error message.

tempnam - creates a unique file name in arbitrary directries.

tmpfile - creates a temporary binary file and opens it for update (w+b)

tmpnam - creates a unique file name, which can safely be used as the name of a temporary file.

ungetc - pushes the character c back onto the named input stream, which must be open for reading.

unlink - deletes a file specified by filename. Any DOS drive, path, and file name can be used as filename. Wildcards are not allowed.
