Need explanation about Oracle documentation (DBMS_LOB.LOADCLOBFROMFILE)

Question

Hello World,
I try to understand Oracle documentation about DBMS_LOB.LOADCLOBFROMFILE function.
I am not shure the explanation is written in a very good english,
but i can't understand a word !!!
Is anybody could explain me in more simple sentences ??
DBMS_LOB.LOADCLOBFROMFILE (
dest_lob IN OUT NOCOPY BLOB,
src_bfile IN BFILE,
amount IN INTEGER,
dest_offset IN OUT INTEGER,
src_offset IN OUT INTEGER,
src_csid IN NUMBER,
lang_context IN OUT INTEGER,
warning OUT INTEGER);
Oracle documentation explanation :
src_csid Character set id of the source (BFILE) file.
lang_context (IN) Language context, such as shift status, for the current
load. (OUT) The language context at the time when the
current load stopped, and what the next load should be using if
continuing loading from the same source. This information is
returned to the user so that they can use it for the continuous
load without losing or misinterpreting any source data. For the
very first load or if do not care, simply use the default 0. The
details of this language context is hidden from the user. One
does not need to know what it is or what’s in it in order to
make the call
warning (OUT) Warning message. This indicates something abnormal
happened during the loading. It may or may not be caused by the
user’s mistake. The loading is completed as required, and it’s up to the
user to check the warning message. Currently, the only possible
warning is the inconvertible character. This happens when the
character in the source cannot be properly converted to a character in
destination, and the default replacement character (e.g., ’?’) is used in
place. The message is defined as warn_inconvertable_char in
DBMSLOB.

I am not kidding. I posted the link but I did not check if it were the same source. Really I do not have time to realize it.
I think you can get a fast answer in SQL & PL/SQL forum.
Good Luck!
