int pmemset_source_from_temporaryW(struct pmemset_source **src, const wchar_t const char *dir);
pmemset_source_from_temporaryU()/pmemset_source_from_temporaryW() function instantiates a new struct pmemset_source** object describing the data source and creates a unnamed temporary file in the provided directory *dir. The temporary file is always created with mode 0600, and the dir must specify an existing directory name. The created file has size 0 and is extended dynamically based on required part size during pmemset_part_map(3).
In case of source from temporary file the pmemset_source_delete(3) function frees *src and sets *src to NULL and closes the temporary file as a result the file is immediately deleted.
The pmemset_source_from_temporaryU()/pmemset_source_from_temporaryW() function return 0 on success or negative error code on failure.
The pmemset_source_from_temporaryU()/pmemset_source_from_temporaryW() can fail with the following errors:
PMEMSET_E_INVALID_SOURCE_PATH - the provided directory path string is NULL or provided path does not exists.
PMEMSET_E_CANNOT_CREATE_TEMP_FILE - cannot create a unique temporary filename.
-ENOMEM - in case of insufficient memory to allocate an instance of struct pmemset_source.
