/** \brief Return the file-path of the key file related
* to the identified shared memory
*
* \b os_posix_findKeyFile tries to find the key file related to \b name
* in the \b temporary directory. The key files are prefixed with \b
* /<temporary directory>/spddskey_.
*
* \b os_posix_findKeyFile first opens the directory \b temporary directory by
* calling \b opendir. Then it reads all entries in serach for any entry
* that starts with the name \b spddskey_ by reading the entry with
* \b readdir. If the a matching entry is found, it calls os_posix_matchKeyFile
* to check if the key file matches the identified \b name. If the
* \b name matches the contents, the entry is found, and the path
* is returned to the caller. The memory for the path is allocated
* from heap and is expected to be freed by the caller.
*
* If no matching entry is found, NULL is returned to the caller.
