Question

How do I create a directory through the Harbour language?

For example, I want to create a folder temp inside the current directory from where the program is running.

Using the function MakeDir(). So just do:

MakeDir("caminho desejado").

Remembering that Harbour is case-insentive and in thesis you can write the name of the function as you like. It returns 0 if the creation occurred ok, or the error number returned by the operating system. Harbour does not usually use exceptions to report errors, except to have a mechanism for this. The function FError() it can be used as an auxiliary.

The function is compatible with Clipper. There are some function aliases.

One way is by using the function MAKEDIR

MAKEDIR("temp")

First of all, I do not recommend creating temporary things in the program folder. The OS usually already has a definition of temp for this.

The function to create a directory is

hb_DirCreate( 'temp' )

Example:

IF hb_DirCreate( cDir ) == 0
   ? "Diretório criado com sucesso"
ENDIF

Which is equivalent to the old Clipper MakeDir. Interestingly, when flag HB_COMPAT_C53 is active when building Harbour, it activates this line:

HB_FUNC_TRANSLATE( MAKEDIR, HB_DIRCREATE )

_{this stands at src/rtl/dirdrive.c}

If you want a more complex path (creation recursive):

hb_DirBuild( 'caminho/composto')

About observing the location of the temp, think that often the application is installed in a location, such as an SSD, and the temporary in a normal HD to avoid premature wear, or even in a RamDisk for higher execution speed. It would be nice to respect the preferences of the system administrator.

To get the location of the system temp:

cLocal := hb_DirTemp()

And it also has hb_FTempCreate, which already takes care of all this that I mentioned and creates the temporary file, and is abstracted by

TempFile([<cDirectory>], [<cExtension>], [<nFileAttr>])

^{the documentation is at the address https://harbour.github.io/doc , but it is in a general reorganization process, a bit confusing to leave permalinks at the moment}
