creating a temporary folder in tmp folder c language

Question

Hi,

How can i create a temporary folder in tmp folder using C++ language.

Edited: This is my code but is showing an error. Actually, i have 3 volumes. Leopard, Development and 10.6 (in Mac OS X) and i want to create a temp directory in current home directory. Here is my code,

// i am confused about this line char* tempdir = "/Volumes/Development/NewFolder.XXXXXX";

if (!mkdtemp(tempdir))

fprintf(stderr, "Not able to create directory");

Answer 1

You can use the boost::Filesystem library function: create_directory( "temp" );

This is very portable and will work under most operating systems.

Boost can be downloaded here.

Answer 2

Under POSIX, you can use mkdtemp to create a directory with a unique name. On Windows, use GetTempPath to retrieve the name of the temp directory, then create a directory with a random name there.

Hello iSight,

Boost is an excellent choice, but one of the problems with boost is that you would probably be downloading a huge amount of sources - if all you need is the filesystem functionality this is a bit of an overkill. Try http://stlplus.sourceforge.net/stlplus3/docs/file_system.html

Also why don't you just use the good old system() function? The string argument to system of course would be platform dependent.
