valueopenTempFile

:: FilePath
Directory in which to create the file
-> String
File name template. If the template is "foo.ext" then the created file will be "fooXXX.ext" where XXX is some random number. Note that this should not contain any path separator characters. On Windows, the template prefix may be truncated to 3 chars, e.g. "foobar.ext" will be "fooXXX.ext".
-> IO (FilePath, Handle)

The function creates a temporary file in ReadWrite mode. The created file isn't deleted automatically, so you need to delete it manually.

The file is created with permissions such that only the current user can read/write it.

With some exceptions (see below), the file will be created securely in the sense that an attacker should not be able to cause openTempFile to overwrite another file on the filesystem using your credentials, by putting symbolic links (on Unix) in the place where the temporary file is to be created. On Unix the O_CREAT and O_EXCL flags are used to prevent this attack, but note that O_EXCL is sometimes not supported on NFS filesystems, so if you rely on this behaviour it is best to use local filesystems only.

Like openTempFile, but opens the file in binary mode. See openBinaryFile for more comments.
