Manual page for UNGETC(3S)
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.
