DESCRIPTION    [Toc]    [Back]

     The  getc_unlocked()  and  getchar_unlocked()  functions are
equivalent to
     their locked counterparts, getc(3) and getchar(3).  However,
     getc_unlocked() and getchar_unlocked() assume that the relevant stream
     has either been previously locked with flockfile(3), or that
it will not
     be accessed by any other thread.

RETURN VALUES    [Toc]    [Back]

     The   return   values  are  as  described  for  getc(3)  and
getchar(3).
