Re: CreateDir

Version 5.5 is the set of command line tools from C++ Builder 5 but does not 
include the VCL, a Delphi-based class library for Windows.  The header files 
ending in .hpp are VCL items so are not supplied.

A substitute set of functions, DirExists, FileExists and CreateDir are shown 
below.
----------------------
#include <windows.h>

const unsigned long NOT_FOUND = 0xFFFFFFFF;

extern "C"
bool WINAPI DirExists(const char *dir_name)
    {
    unsigned long attribs;

    attribs = GetFileAttributes(dir_name);
    return (attribs != NOT_FOUND) &&
        ((attribs & FILE_ATTRIBUTE_DIRECTORY) != 0);
    }

extern "C"
bool WINAPI FileExists(const char *file_name)
    {
    unsigned long attribs;

    attribs = GetFileAttributes(file_name);
    return (attribs != NOT_FOUND) &&
        ((attribs & FILE_ATTRIBUTE_DIRECTORY) == 0);
    }

extern "C"
bool WINAPI CreateDir(const char *dir_name)
    {
    return ! DirExists(dir_name) && CreateDirectory(dir_name, NULL);
    }
----------------------

In addition there are other supplied functions which can be used for that 
such as those Mr Maeder mentions.

Hello:

I would like to use "DirectoryExists" and "CreateDir", I
used  the bcb5.hlp, 
it say to include "Filectrl.hpp", but such a file is not included in
the 
free version 5.5.
What's the problem? is there any other alternative?

Thanks
Maurice


#include "Filectrl.hpp"

void main()
{
if(!DirectoryExists("c:\\tmp"))
   CreateDir("c:\\tmp");
}

Error E2209 e:\my_data\prog\tc\test.cpp 1: Unable to open include file 
'Filectr.hpp'
Error E2268 e:\my_data\prog\tc\test.cpp 5: Call to undefined function 
'Directory
Exists' in function main()
Error E2268 e:\my_data\prog\tc\test.cpp 6: Call to undefined function 
'CreateDir
' in function main()
*** 3 errors in Compile ***

I have no idea.

Probably.

NB: The return type of main() has to be int.

E.g.:

#include <sys/stat.h>
#include <sys/types.h>
#include <dirent.h>
#include <dir.h>

int main()
{
  if (DIR *dir = opendir("c:\\tmp"))
  {
    ; // directory exists and is accessible
    closedir(dir);
  }
  else if (mkdir("c:\\tmp")==0)
    ; // directory successfully created
  else
    ; // error handling
}

opendir(), closedir() and mkdir() are POSIX functions. The #includes
you have to use may vary; the ones given above work on C++BuilderX.

[FWIW, there is no <dir.h> on Linux (and it's not needed), and mkdir()

Did you notice the mention to Sysutils Unit?
