int _fgetchar(void); 

wint_t _fgetwchar(void); 

Description 

Reads a character from stdin. 

_fgetchar returns the next character from stdin. It is defined as fgetc(stdin).

On success _fgetchar returns the character read after converting it to an int without sign extension. On end-of-file or error it returns EOF. 

Example  

#include <stdio.h>
int main(void)
{
   char ch;
   /* prompt the user for input */
   printf("Enter a character followed by <Enter>: ");
   /* read the character from stdin */
   ch = fgetchar();
   /* display what was read */
   printf("The character read is: '%c'\n", ch);
   return 0;
}
