- UNGETC(3) Minix Programmer's Manual UNGETC(3)
- NAME
- ungetc - push character back into input stream
- SYNOPSIS
- #include <stdio.h>
- int ungetc(int c, 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(3) erases all memory of pushed back characters.
- SEE ALSO
- getc(3), setbuf(3), fseek(3).
- DIAGNOSTICS
- Ungetc returns EOF if it can't push a character back.
