converting a program from unix to windows

hello,

i'm wondering if anybody out there could point me to a tutorial or FAQ on porting a unix C program to windows?

specifically, i'm getting an error when i compile with the following functions defined:

Code:

---

srand( (unsigned)time( (time_t *) 0 ));

---

to seed srand. the error is:

'time': identifier not found, even with argument-dependent lookup

also,

Code:

---

mkdir(theFolder, 00777);

---

with the same error code. it may be my headers are incorrect, so i'll list them too:

#include <iostream>
#include <tchar.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <ctype.h>
#include <sys/types.h>
#include <sys/stat.h>

any help or advice would be appreciated. i'm using visual studio to compile.

time() is in <time.h>. mkdir() is often in <unistd.h>.

here you go:

Code:

---

<stdlib.h>
<time.h>

srand( (unsigned)time( (time_t *) 0 ));

---

As for mkdir, since dos died, I'm not too sure, sorry...

mkdir() is a POSIX function.

Why are you including iostream? That's for C++.

mkdir() is one of the few POSIX standard functions that most Windows compiler also support.

Waltr: there are many *nix functions that have no MS-Windows equivalents, and others have different function names with similar functionality. For example, *nix opendir() and readir(), MS-Windows equivalents are ReadFirstFile() and ReadNextFile().

hi all,

thanks for the replies. <itsme> i'm not sure why i had <iostream> in there. it's not necessary so i've removed it.

<time.h> has solved my

Code:

---

srand( (unsigned)time( (time_t *) 0 ));

---

problem, but i still can't seem to get the mkdir() function to work.

any other suggestions are welcome, if i solve it myself i'll post the answer. thanks again!

It looks like you should be able to use mkdir() if you #include <direct.h>

Besides, that wasn't my point. My point was that is isn't a DOS function:

Which is also your point. :)

The Visual Studio compilers have a _mkdir function in that header... perhaps that can be used.
