What is conio.h in c?
Conio.h is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor it is defined by POSIX. This header declares several useful library functions for performing “console input and output” from a program.
The library functions declared by conio.h vary somewhat from compiler to compiler. As originally implemented in Lattice C, the various functions mapped directly to the first few DOS INT 21H functions.
Following are the list of conio.h functions list in c programming language.
| Function Name | Descriptions |
| kbhit | Determines if a keyboard key was pressed |
| cgets | Reads a string directly from the console |
| cscanf | Reads formatted values directly from the console |
| putch | Writes a character directly to the console |
| cputs | Writes a string directly to the console |
| cprintf | Formats values and writes them directly to the console |
| clrscr | Clears the screen |
| getch | Get char entry from the console |
