Function Documentation

ungetc()

int ungetc	(	int	character,
		FILE *	stream
	)

Unget character from stream.

A character is virtually put back into an input stream, decreasing its internal file position as if a previous getc operation was undone.

Parameters

character	The int promotion of the character to be written.
stream	Pointer to a FILE object that identifies the stream to be closed.

Returns

On success, the character put back is returned. If the operation fails, EOF is returned.
