Prototype

int putch(int c);

Description

Outputs character to screen.

putch outputs the character c to the current text window. It is a text mode function performing direct video output to the console. putch does not translate linefeed characters (\n) into carriage-return/linefeed pairs.

The string is written either directly to screen memory or by way of a BIOS call, depending on the value of the global variable _directvideo.

Remarque :  This function should not be used in Win32 GUI applications.

Return Value

On success, putch returns the character printed, c. On error, it returns EOF.

Example

 #include <stdio.h>
 #include <conio.h>
 int main(void)
 {
   char ch = 0;
   printf("Input a string:");
   while ((ch != '\r'))
   {
     ch = getch();
     putch(ch);
   }
   return 0;
 }
