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; }
