Synopsis:
    #include <stdio.h>
    int getchar( void );

Description:
    The getchar function is equivalent to  getc with the argument  stdin.

Returns:
    The getchar function returns the next character from the input stream
    pointed to by  stdin.  If the stream is at end-of-file, the end-of-file
    indicator is set and getchar returns  EOF.  If a read error occurs, the
    error indicator is set and getchar returns  EOF.  When an error has
    occurred,  errno contains a value indicating the type of error that has
    been detected.

See Also:
    fgetc, fgetchar, getc

Example:
    #include <stdio.h>

    void main()
      {
        FILE *fp;
        int c;

        fp = freopen( "file", "r", stdin );
        while( (c = getchar()) != EOF )
          putchar(c);
        fclose( fp );
      }
