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.

Note: 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;
}
