### GreCreateJournalFile Parameter - cSize

cSize (ULONG) - input Size.

If greater than 0, cSize is an indication as to how large the file must be. If flOption is JNL_USERRAM_FILE, cSize must be greater than 0 and is the size of the buffer, which cannot be extended.

If cSize is 0, the calling routine does not know the size of the file.
