How to create a Directory in C++?

[Rajesh N Thipse]

Hi,
Files can be created using _creat.
Similarly, is there a function to create a directory?

Really? I don't know such function in the Standard library.

Similarly, no. Check the programming manual for your OS.

--------------------
In VC++, the following piece of code generates "temp" file
#include <io.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>

void main( void )
{
int fh = _creat( "temp", _S_IREAD | _S_IWRITE );
if( fh == -1 )
perror( "Couldn't create data file" );
else
{
printf( "Created data file.\n" );
_close( fh );
}
}

Output

Created data file.

Similarly, no. Check the programming manual for your OS.

--------------------
However, whether one uses _creat for creating a file or some other
function to do so is immaterial. The real question of creating a
directory remains unanswered.
I've checked programming manual, but didn't get much of help. Also
if I go for a OS specific function there can be an issue of
portability later.

But that is not standard C++. It uses Windows-specific functions. Here's
what I got when I tried to compile it under Mac OS X:

[Jon-Bells-Computer:~/Documents/c++] jtbell% c++ create.cpp
create.cpp:1:16 : io.h: No such file or directory
create.cpp:8: error: `main' must return `int'
create.cpp: In function `int main(...)':
create.cpp:9: error: `_S_IREAD' undeclared (first use this function)
create.cpp:9: error: (Each undeclared identifier is reported only once for
each
function it appears in.)
create.cpp:9: error: `_S_IWRITE' undeclared (first use this function)
create.cpp:9: error: `_creat' undeclared (first use this function)
create.cpp:15: error: `_close' undeclared (first use this function)

Files can be created using _creat. No, not in C++.

Not in standard C++, but it is possible with boost::filesyst em
