uunnggeettcc() -- STDIO Function (libc)

Return character to input stream
#iinncclluuddee <ssttddiioo.hh>
iinntt uunnggeettcc (_c, _f_p)
iinntt _c; FFIILLEE *_f_p;

uunnggeettcc() returns the character _c to the stream _f_p.  _c can then be read by a
subsequent call  to ggeettcc(), ggeettss(),  ggeettww(), ssccaannff(), or  ffrreeaadd().  No more
than one character  can be pushed back into any  stream at once.  A call to
ffsseeeekk() will nullify the effects of a previous uunnggeettcc().

uunnggeettcc()  normally returns  _c. It  returns EEOOFF if  the character  cannot be
pushed back.
