That character will be returned by the next .I getc call on that stream. .I Ungetc returns .IR c . .PP 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. .PP .IR Fseek (3) erases all memory of pushed back characters. .SH "SEE ALSO" getc(3), setbuf(3), fseek(3) .SH DIAGNOSTICS .I Ungetc returns .SM .B EOF if it can't push a character back.
