compiling C code at visual C++ 6.0

hi, when i compile my c code at visual C++ 6.0, i got some errors and i can't fix it, please help..

my C file uses the unistd.h and the code is

Code:

/* This is defined as a real library function to allow autoconf
   to verify its existence. */
int ftruncate(int, off_t);
__CRT_INLINE int ftruncate(int __fd, off_t __length)
{
  return _chsize (__fd, __length);
}

errors:
error C2081: 'off_t' : name in formal parameter list illegal
error C2054: expected '(' to follow '__CRT_INLINE'
error C2146: syntax error : missing ')' before identifier '__length'
error C2081: 'off_t' : name in formal parameter list illegal
error C2082: redefinition of formal parameter 'ftruncate'
error C2146: syntax error : missing ',' before identifier '__length'
error C2059: syntax error : ')'
error C2143: syntax error : missing ';' before '{'

That appears to be a cut and paste from compiler generated code. Can you post your source code?

unistd.h source code:

Code:

/*
 * This file is part of the Mingw32 package.
 *
 * unistd.h maps (roughly) to io.h
 */

#ifndef _UNISTD_H
#define _UNISTD_H

#include <io.h>
#include <process.h>

#define __UNISTD_GETOPT__
#include <getopt.h>
#undef __UNISTD_GETOPT__

#ifdef __cplusplus
extern "C" {
#endif

/* This is defined as a real library function to allow autoconf
   to verify its existence. */
int ftruncate(int, off_t);
__CRT_INLINE int ftruncate(int __fd, off_t __length)
{
  return _chsize (__fd, __length);
}

#ifdef __cplusplus
}
#endif

#endif /* _UNISTD_H */

No, not the header - the code YOU wrote!!

unistd.h is a UNIX header, not a Windows header.

MinGW provides it, but I have no idea how will it works, if at all.
