ALLOCA(3)

NAME
       alloca - memory allocator

SYNOPSIS
       #include <<stdlib.h>>

       void *alloca( size_t size);

DESCRIPTION
       The  alloca  function allocates size bytes of space in the
       stack frame of the caller.  This temporary space is  auto-
       matically freed on return.

RETURN VALUES
       The  alloca function returns a pointer to the beginning of
       the allocated space.  If the  allocation  failed,  a  NULL
       pointer is returned.

CONFORMING TO
       There  is  evidence  that  the alloca function appeared in
       32v, pwb, pwb.2, 3bsd, and 4bsd.  There is a man page  for
       it in BSD 4.3.  Linux uses the GNU version.

BUGS
       The alloca function is machine dependent.
