NAME
       ungetc - push character back into input stream

SYNOPSIS
       #include <stdio.h>

       int ungetc(int c, FILE *stream);

DESCRIPTION
       Ungetc  pushes  the character c (converted to an unsigned char) back on
       an input stream.	 That character will be returned by the next getc call
       on that stream.

       One  character  of  pushback  is guaranteed provided something has been
       read from the stream and the stream is actually buffered.  Attempts  to
       push EOF are rejected.

       Fseek(3S),  fsetpos(3S), or rewind(3S) erases all memory of pushed back
       characters.

RETURN VALUE
       Ungetc returns the character pushed back after conversion,  or  EOF  if
       unsuccessful.

SEE ALSO
       getc(3S), setbuf(3S), fseek(3S), fsetpos(3S), rewind(3S)
