you, have to provide this parameter (information) for the function, Unlike [out] u receive this parameter from the function
Example
bool TextGetSize( const string text, // text string uint& width, // buffer width in pixels uint& height // buffer height in pixels );
Parameters
text
[in] String, for which length and width should be obtained.
width
[out] Input parameter for receiving width.
height
[out] Input parameter for receiving height.
Thanks.

My apologies for this somewhat noob question but I'm not all that up to speed with MQL and reading through the documentation I see things like:-
Parameters
ticket
[in] Order index or order ticket depending on the second parameter.
select
[in] Selecting flags. It can be any of the following values:
SELECT_BY_POS - index in the order pool,
SELECT_BY_TICKET - index is order ticket.
My questions what does the [in] mean?
Thanks in advance.
