    UNGETC(3S)	    UNIX Programmer's Manual	       UNGETC(3S)

    NAME
         ungetc - push character back into input stream

    SYNOPSIS
         #include <stdio.h>

         ungetc(c, stream)
         FILE *stream;

    DESCRIPTION
         Ungetc pushes the character c back on an input stream.  That
         character will be returned by the next getc call on that
         stream.  Ungetc returns c.

         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) erases all memory of pushed back characters.

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

    DIAGNOSTICS
         Ungetc returns EOF if it can't push a character back.
