Hi All!
I made C++ library that use IRIX(unix?) mmap funtion (and his family:
munmap etc).
 I port it to DJGPP without this but it is not as effective as I
expected. Have anybody  a implementation of mmap for DJGPP? 
There is a head of man page:

NAME
     mmap - map pages of memory

SYNOPSIS
     #include <sys/types.h>
     #include <sys/mman.h>

     void *mmap(void *addr, size_t len, int prot, int flags, int fd,
off_t
          off);

DESCRIPTION
     The function mmap establishes a mapping between a process's address
space
     and a virtual memory object.  The format of the call is as follows:

          pa = mmap(addr, len, prot, flags, fd, off);

     mmap establishes a mapping between the process's address space at
an
     address pa for len bytes to the memory object represented by the
file
     descriptor fd at offset off for len bytes.  The value of pa is an
     implementation-dependent function of the parameter addr and values
of
     flags, further described below.  A successful mmap call returns pa
as its
     result.  The address ranges covered by [pa, pa + len) and [off, off
+
     len) must be legitimate for the possible (not necessarily current)
     address space of a process and the object in question,
respectively.

			Sorry about my english
			Thanks for any helps.
