    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'

    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 */

    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.
