How to implement getch() function of C in Linux?

What is the equivalent Linux version of the conio.h header file from MS-DOS?

Is there a way to replace its functionality? e.g. getch()

I\'m using gcc and the text editor Geany to compile the C code.

回答1:

conio.h is a C header file used in old MS-DOS compilers to create text user interfaces. Compilers that targeted non-DOS operating systems, such as Linux, Win32 and OS/2, provided different implementations of these functions.

The #include <curses.h> will give you almost all the functionalities that was provided in conio.h

nucurses need to be installed at the first place

In deb based Distros use

sudo apt-get install libncurses5-dev libncursesw5-dev

And in rpm based distros use

sudo yum install ncurses-devel ncurses

For getch() class of functions, you can try this

回答2:

The original conio.h was implemented by Borland, so its not a part of the C Standard Library nor is defined by POSIX.

But here is an implementation for Linux that uses ncurses to do the job.

回答3:

A popular Linux library which has similar functionality would be ncurses.

回答4:

That is because is does not exist, since it is bounded to Windows.

Use the standard functions from <stdio.h> instead, such as getc

The suggested ncurses library is good if you want to write console-based GUIs, but I don\'t think it is what you want.
