Can somebody please tell me how to work around this problem?

I'm working on a program that needs to be able to execute commands in a temporary file using /bin/sh. The problem is that temporary files made using
KTemporaryFile vanish the moment I call exec.

Since I need to know the name of the file I am using is all of the
recommended subroutines in the C library are out of the picture as well.

You need to keep the "KTemporaryFIle" object around, because objects created like below will be automatically cleaned up by the compiler when they go out of scope. When the KTemporaryFile instance is destroyed, the file will be deleted also.

Code: Select all

KTemporaryFile myFile;

You need to create the KTemporaryFile as follows:

Code: Select all

KTemporaryFIle * myFile = new KTemporaryFile( <constructor contents> );

Or turn its "auto remove" feature off. See QTemporaryFile (its base class)

Cheers,
