Writes a character directly to the console.
![conio library conio library](https://billthefarmer.github.io/blog/images/2020/08/RSX.png)
Reads formatted values directly from the console.
Reads a string directly from the console. Library functions like getch(), getche() etc are also used to get input from the user but on submitting the code, the compiler shows error atPuts the character c back into the keyboard buffer. Reads a character directly from the console without buffer, but with echo. Reads a character directly from the console without buffer, and without echo. Another example is SyncTERM#Libraries | SyncTERM's ciolib.ĭetermines if a keyboard key was pressed. The version done by DJ Delorie for the DJGPP|GO32 extender is particularly extensive. But the library supplied with Borland's Turbo C did not use the DOS API but instead accessed video RAM directly for output and used BIOS interrupt calls they also have additional functions inspired on the successful Turbo Pascal library.Ĭompilers that targeted non-DOS operating systems, such as Linux, Win32 and OS/2, provided different implementations of these functions. As originally implemented in Lattice C, the various functions mapped directly to the first few DOS int 21h functions. The library functions declared by conio.h vary somewhat from compiler to compiler. Some embedded systems are using a conio-compatible library.
Most C compilers that target UNIX and Linux do not have this header and do not supply the library functions. Contains classes and functions used by the C++ Standard Library to allocate memory to the C++ Standard Library containers.
CONIO LIBRARY WINDOWS
Most C compilers that target DOS, Windows 3.x, Phar Lap (company)|Phar Lap, DOSX, OS/2, or Win32 have this header and supply the associated library functions in the default C library. This header declares several useful library functions for performing "console input and output" from a program.
CONIO LIBRARY ISO
It is not described in The C Programming Language (book)| The C Programming Language book, and it is not part of the C standard library, ISO C nor is it required by POSIX. Conio.h is a C (programming language)|C header file used in old MS-DOS compilers to create text user interfaces.
