NAME
       ungetc -	 Pushes a character back into the input stream

LIBRARY
	Standard C Library (libc.a)

SYNOPSIS
       #include <stdio.h>

       int ungetc(
	       int c,
	       FILE *stream);

PARAMETERS
       Specifies  a  byte to be inserted into the input stream.	 Specifies the
       input stream.

DIFFERENCES
       vms-vaxc(5): OpenVMS VAX C vs DEC C Differences

       With the DEC C RTL, a call to ungetc(3)	clears	the  end-of-file  flag
       (EOF) for the file.  With the VAX C RTL it does not.

       In  the	DEC  C	RTL, a call to a file position routine (e.g. fseek(3))
       causes the character pushed back by a call to  ungetc(3)	 to  be	 lost.
       The VAX C RTL does not discard this character in this situation.
