Yes, i dont' want that.

unfortunately it has a very ugly interface and takes a 5th argument, depending
on the flags:

       void * mremap(void *old_address, size_t old_size , size_t new_size, int
       flags);
[]
       The flags bit-mask argument may be 0, or include the following flag:
[]
       MREMAP_FIXED (since Linux 2.3.31)
              This  flag  serves  a  similar  purpose to the MAP_FIXED flag of
              mmap(2).  If this flag is specified,  then  mremap()  accepts  a
              fifth  argument,  void  *new_address,  which  specifies  a page-
              aligned address to which the mapping must be moved.  Any  previ-
              ous  mapping  at  the address range specified by new_address and
              new_size  is  unmapped.   If  MREMAP_FIXED  is  specified,  then
              MREMAP_MAYMOVE must also be specified.
